Consumer (food chain) Living creatures that eat organisms from a different population A consumer in a is a living creature that eats organisms from a different population. A consumer is a and a producer is an, Like sea angels, they take in organic moles by consuming other organisms, so they are commonly called consumers.
Heterotrophs can be classified by what they usually eat as herbivores, carnivores, omnivores, or decomposers. On the other hand, autotrophs are organisms that use energy directly from the sun or from chemical bonds. Autotrophs are vital to all because all organisms need organic molecules, and only autotrophs can produce them from inorganic compounds.
Autotrophs are classified as either photoautotrophs (which get energy from the sun, like plants) or chemoautotrophs (which get energy from chemical bonds, like certain bacteria). Consumers are typically viewed as predatory animals such as meat-eaters.
- However, herbivorous animals and parasitic fungi are also consumers.
- To be a consumer, an organism does not necessarily need to be carnivorous; it could only eat plants (producers), in which case it would be located in the first level of the food chain above the producers.
- Some carnivorous plants, like the, are classified as both a producer and a consumer.
Consumers are therefore anything that eats; hence the word consume which means to eat.

What distinguishes primary consumers?
On a sawgrass prairie in the Florida Everglades, an alligator ( Alligator mississippiensis ) lazes on the bank of a slow-moving water channel. A great egret (Ardea alba) stalks fish in the shallows. A grasshopper ( Brachystola magna ) chews on an aster leaf.
- A raccoon (Procyon lotor) digs in the mud for freshwater mussels.
- These animals are quite different from one another and live in different ways, but they have something in common: In this ecosystem, they are all consumers,
- Within every ecosystem, organisms interact to move energy around in predictable ways.
These interactions can be represented by what scientists call a trophic pyramid. Primary producers —plants, algae, and bacteria —make up the base of the pyramid, the first trophic level, Through a process called photosynthesis, producers capture energy from the sun and use it to create simple organic molecules, which they use for food.
- Consumers constitute the upper trophic levels,
- Unlike producers, they cannot make their own food.
- To get energy, they eat plants or other animals, while some eat both.
- Scientists distinguish between several kinds of consumers,
- Primary consumers make up the second trophic level,
- They are also called herbivores,
They eat primary producers —plants or algae —and nothing else. For example, a grasshopper living in the Everglades is a primary consumer, Some other examples of primary consumers are white-tailed deer that forage on prairie grasses, and zooplankton that eat microscopic algae in the water.
- Next are the secondary consumers, which eat primary consumers,
- Secondary consumers are mostly carnivores, from the Latin words meaning “meat eater.” In the Everglades, egrets and alligators are carnivores,
- They eat only other animals.
- Most carnivores, called predators, hunt and kill other animals, but not all carnivores are predators,
Some, known as scavengers, feed on animals that are already dead. Some consumers feed on live animals but do not kill them. For example, small arachnids called ticks attach themselves to other animals and feed on their blood, but ticks are not considered predators,
- They are instead called parasites,
- Some secondary consumers eat both plants and animals.
- They are called omnivores, from the Latin words that mean “eats everything.” A raccoon is an example of an omnivore ; it eats plant matter such as berries and acorns, but it also catches crayfish, frogs, fish, and other small animals.
Ecosystems can also have tertiary consumers, carnivores that eat other carnivores, A bald eagle is an example of a tertiary consumer you might see near the coastal mangrove islands of the Everglades, Its diet includes predatory fish that eat algae -eating fish, as well as snakes that feed on grass-eating marsh rabbits.
What is the difference between a primary and secondary consumer quizlet?
Primary consumers are animals that eat primary producers; they are also called herbivores (plant-eaters). Secondary consumers eat primary consumers. They are carnivores (meat-eaters) and omnivores (animals that eat both animals and plants).
What is an example of a primary and secondary consumer?
Primary consumers vary with the type of an ecosystem. For example, in a forest ecosystem, deer or giraffe is a primary consumer whereas in a grassland ecosystem, cow or goat is a primary consumer. SECONDARY CONSUMERS: These are carnivores and feed on primary consumers and producers. For example, dogs, cats, birds etc.
What is the difference between primary to secondary to tertiary consumers?
Primary consumers refer to the organisms that feed on primary producers, and secondary consumers refer to the organisms that feed on primary consumers while tertiary consumers refer to the animals that obtain their nutrition by eating primary consumers and secondary consumers.
What is a secondary consumer?
Definition noun, plural: secondary consumers Any organism that consumes or feeds largely on primary consumers, as well as autotrophs Supplement A food chain is a feeding hierarchy showing the various trophic levels. A trophic level is a position in a food chain or an ecological pyramid,
- The organisms grouped into a trophic level share a common mode by which they obtain nourishment.
- There are three fundamental ways organisms obtain nourishment.
- Producers or autotrophs are organisms that obtain food from inorganic sources and are capable of synthesizing their food (through photosynthesis ).
In the ecological pyramid or a food chain, producers are at the base. They are followed by consumers that obtain nourishment by feeding on organic matter, such as plants and animals. The last group in the food chain or ecological pyramid and is located on top level is the decomposers or the detritivores,
- Consumers are organisms that derive their nutrients largely from an organic matter (e.g. animals).
- They are not capable of photosynthesis and therefore rely on hunting, parasitism, predation, etc.
- To obtain food.
- In a food chain, consumers may be further grouped into primary consumers, secondary consumers, and tertiary consumers.
Secondary consumers are largely comprised of carnivores that feed on the primary consumers or herbivores, Other members of this group are omnivores that not only feed on primary consumers but also on producers or autotrophs. An example is a fox eating rabbit.

What is the difference between the two types of consumers?
Primary consumers: Animals that mainly depend on plants for their food are called herbivores. Some examples of herbivores are cows, goats and deer. Herbivores are also called primary consumers. Secondary consumers: Animals that eat the flesh and meat of other living animals are called carnivores.
What are primary to secondary consumers?
Food chains – Now, we can take a look at how energy and nutrients move through a ecological community. Let’s start by considering just a few “who eats whom” relationships – that is, by looking at a food chain. A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.
At the base of the food chain lie the primary producers, The primary producers are autotrophs, and are most often photosynthetic organisms (such as plants, algae, or cyanobacteria). The organisms that eat the primary producers are called primary consumers, Primary consumers are usually herbivores (plant-eaters), though they may be algae or bacteria eaters. The organisms that eat the primary consumers are called secondary consumers, Secondary consumers are generally meat-eaters ( carnivores ). The organisms that eat the secondary consumers are called tertiary consumers, These are carnivore-eating carnivores, like eagles or big fish. Some food chains have additional levels, such as quaternary consumers (carnivores that eat tertiary consumers). Organisms at the very top of a food chain are called the apex consumers,
We can see examples of these levels in the diagram below. The green algae are primary producers that get eaten by mollusks (the primary consumers). The mollusks then become lunch for the slimy sculpin fish, a secondary consumer, which is itself eaten by a larger fish, the Chinook salmon (tertiary consumer).
Each of the categories above is called a trophic level, and it reflects how many transfers of energy and nutrients (how many consumption steps) separate an organism from the food chain’s original energy source, such as light. As we’ll explore further below, assigning organisms to trophic levels isn’t always clear-cut.
For instance, humans are omnivores that can eat both plants and animals.
What is the difference between primary meaning and secondary meaning?
Primary sources are firsthand, contemporary accounts of events created by individuals during that period of time or several years later (such as correspondence, diaries, memoirs and personal histories). These original records can be found in several media such as print, artwork, and audio and visual recording.
Examples of primary sources include manuscripts, newspapers, speeches, cartoons, photographs, video, and artifacts. Primary sources can be described as those sources that are closest to the origin of the information. They contain raw information and thus, must be interpreted by researchers. Secondary sources are closely related to primary sources and often interpret them.
These sources are documents that relate to information that originated elsewhere. Secondary sources often use generalizations, analysis, interpretation, and synthesis of primary sources. Examples of secondary sources include textbooks, articles, and reference books.
What are 2 different secondary consumers?
Secondary Consumer Examples Bears, which eat ungulates such as deer. Birds, which eat plant-eating insects. Wolves, which eat a mix of large and small-bodied herbivores. Fish, which eat zooplankton that survive off photosynthetic phytoplankton.
What are secondary consumers examples?
Conclusion – From the following article, we can conclude that Secondary consumers are organisms that obtain energy from primary consumers. Herbivores, or species that consume only autotrophic plants, are always the primary consumers. Secondary consumers, on the other hand, might be either carnivores or omnivores.
Who are primary customers?
You might think you have a customer-driven strategy, but it’s not always obvious who your most important customers are. Writing for Harvard Business Review, Robert Simons describes the term “customer” as one of the most elastic in management theory. If a primary customer is not identified, customer-based strategies are useless, insists Simons.
- To illustrate, the author contrasts Yahoo’s strategy with that of Google.
- Yahoo spread resources across entertainment and finance media while underinvesting in search, resulting in a “messy and confusing” website.
- Google, meanwhile, focused on users interested in technology and new applications.
- It allocated resources to its engineers and techs, who were free to innovate.
The goal of the company was to build the best technology for multiple applications, such as search, Android and maps. The clear business model and value proposition saw them transform into a giant, leapfrogging Yahoo in the process. The bottom line, insists Simons, is that the primary customer defines the strategy and, ultimately, the business.
- Simons presents a four-step customer-driven framework to help executives build successful business models: 1) Identify your primary customer.
- The lesson from the likes of Google is that your most important customers are those that can unlock the most value in your business, rather than those that generate the most revenue.
The primary customer might be the consumer or end user of a product or service, or an intermediary such as a broker or reseller. Identifying the most appropriate primary customer requires an assessment of each customer group along three dimensions: • Perspective.
- This, explains Simons, “refers to the culture, mission, and folklore of a business, often revealed in stories about important events or people in the company’s history it is the lens through which executives consider opportunities and strategic direction”.
- The author uses the examples of Apple’s Steve Jobs’s perfectionism over product design and Amazon’s Jeff Bezos’s zealousness about giving shoppers a superior experience.
• Capabilities. These are the company’s embedded resources, such as Google’s technology, Amazon’s logistics, and P&G’s superior brand marketing. • Profit potential. This is a customer’s ability to deliver profits. This does not necessarily refer to the customers who are able to pay premium prices – Simons points out Walmart has demonstrated that substantial profits can be achieved through becoming the choice of a high volume of cost-conscious customers.
Your primary customer is the group that best satisfies all three dimensions.2) Understand what your primary customer values. Some customers want the lowest price, others want good customer service, others still want the best quality – and some don’t even know exactly what they value most. Simons recommends refining your understanding of your customers through data on buying habits, preferences and search history.3) Allocate resources.
Once the primary customer and correct values have been identified, the appropriate business model can be adopted and sufficient resources allocated. Simons lists the five basic configurations to choose from: • Low price. For primary customers looking for the lowest price, “centralised operating functions (such as merchandising and distribution) should receive the bulk of organisational resources”.
- Local value creation.
- If your customers like products or services that are specific to their locale, enable managers to tailor customer offerings by pushing resources out to their regions.
- Global standard of excellence.
- If customers want the best possible technology or brand available, organise resources around global business units defined by product lines.
• Dedicated service relationship. Simons explains: “If your customer is looking for an ongoing, deeply embedded service relationship, you should organise like IBM. Customer teams in industry-based ‘verticals’ marshal and coordinate product and service delivery from centralised, product-based ‘horizontal’ units.” • Expert knowledge.
If the primary customer seeks expert technical knowledge, R&D should be the focus of the company’s resources.4) Make the control process interactive. Your business model might be successful today, but it might not survive tomorrow. Disruption can occur in the shape of changing customer tastes, new technologies or new entrants in the marketplace.
Therefore, you need to continually gather information on the shifting competitive environment – especially changes likely to affect your primary customer’s behaviour. Simons advises that managers should continually ask: What has changed? Why? What are we going to do about it? If there are changes in profit potential, your choice of primary customer might change.
What are 5 examples of primary consumers?
Examples of primary consumers can include rabbits, bears, giraffes, flies, humans, horses, and cows.
What are 3 different secondary consumers?
2. Examples of Terrestrial Secondary Consumers – Terrestrial environments range from freezing habitats with negative temperatures to virtually waterless desserts around the equator. Secondary consumers have features and characteristics that enable them to survive in various types of terrestrial ecosystems.
In temperate regions, for example, you will find secondary consumers such as dogs, cats, moles, and birds. Other examples include foxes, owls, and snakes. Wolves, crows, and hawks are examples of secondary consumers that obtain their energy from primary consumers by scavenging. In light of the fact that other mammals could easily hunt humans, humans were classed as secondary consumers.
But that has since changed, thanks to evolution and technological development; humans now occupy the tertiary consumer category. As stated earlier in the article, secondary consumers can sometimes also be classified as primary or secondary consumers based on the environment.
Why do primary consumers get more energy than secondary consumers?
Whenever a consumer eats something, a certain amount of the available energy from the food item passes to the consumer, but not all of the energy in that food item is accessible to the consumer. The image below shows a visual of energy transfer and how it is broken down. Thus, a primary consumer is going to be more efficient than a secondary consumer. A secondary consumer is going to be more efficient than a tertiary consumer. In the image below, the ground squirrel consumes the plant but then the fox consumes the squirrel. Primary producers (the plant in the first image) harvest their energy from the sun. When energy goes from one level in the food chain to the next, anywhere between 5-20% of the energy from the previous level is transferred. Meaning that the lower one goes in the food chain, the more of that original energy (from the sun) is used. Whether 5% of the energy is transferred or 20% depends on the environment, the quality of the food item actually being consumed, and other factors.10% is often used in diagrams for an average.

What do secondary consumers eat?
Types of Secondary Consumers – Secondary consumers can be sorted into two groups: carnivores and omnivores. Carnivores only eat meat, or other animals. Some secondary consumers are large predators, but even the smaller ones often eat herbivores bigger than they are in order to get enough energy.
- Spiders, snakes, and seals are all examples of carnivorous secondary consumers.
- Omnivores are the other type of secondary consumer.
- They eat both plant and animal materials for energy.
- Bears and skunks are examples of omnivorous secondary consumers that both hunt prey and eat plants.
- However, some omnivores are simply scavengers.
Instead of hunting, they eat the excess animal remains that other predators leave behind. Opossums, vultures, and hyenas are some animals that gain energy through scavenging.
What are the differences between consumers?
Customer is the one who is purchasing the goods. Consumer is the one who is the end user of any goods or services. Consumers are unable to resell any product or service. Customers need to purchase a product or service in order to use it.
What are the differences between the 3 types of consumers?
Aim 2-What are the three types of consumers? – courage6science Do Now:
- By the end of this lesson, you should be able to:
- 1. Define the three types of consumers
2. Give examples of the three types of consumers.

- An omnivore eats _both plants and animals_.10.
- A couple examples of omnivores: a) _humans_ b) _bears_11.
Examples of what those omnivores eat: a) _salad and chicken_ b) _berries and salmon_
- Let’s do examples together:
- We’ll write three examples of each type of consumer and one thing each organism eats.
Herbivores Carnivores Omnivores
- Independent Practice:
Choose one of the three tasks to complete for independent practice. If you finish your task and have enough time, you can do another one.1. Make a Google Presentation that follows the same format as Aim 1’s Google Presentation. To do this, you would make a slide for the definition of each category: herbivores, carnivores, and omnivores.
Those slides would be followed by slides with example organisms from each category. Make slides showing what they eat, as well. Finish with a summary slide that includes two paragraphs about the differences between the three types of consumers.2. Draw a picture of two producers, three herbivores, three carnivores, and three omnivores all in the same place together.
Draw arrows showing which organism eats which.3. Write a song or a poem about the three types of consumers. Give examples of each type, and tell about the relationship between them. Exit Slip: Use this picture to answer questions 2 and 3. The arrows to the organism show what it eats.
Unit 6 Food Webs Aim 2 Exit Slip Homework: Whichever of the following two tasks you did not do during class, do the other for homework.

How do you determine primary consumers?
Life on the Food Chain – Have you ever wondered why we can’t seem to feed the world’s hungry? It’s a complex issue, but it might surprise you to learn that it’s not because there isn’t enough food; current agricultural capacity, based on current technology, exists to feed as many as 10 billion people.
The Earth’s population is “only” about 7 billion. The big question really is: If we want to feed everyone, what would everyone need to eat? To answer that question, download this excel spreadsheet and try plugging in some numbers. Example : One acre of a grain crop could be used to feed cattle, and then the cattle could be used to feed people.
If 50% of the energy is lost to the cattle, you could feed twice as many people if you fed them the grain directly. Another way of looking at it is that it would only take a half acre of land to feed the people grain, but a whole acre if you feed the grain to the cattle and the cattle to the people.
A common practice to grow cattle faster is to feed them ground up animal protein. This means that when we eat the meat from the cow, we’re at the tertiary level or higher. The loss of energy between trophic levels may also be even higher. Recent studies suggest that only ~10% of energy is converted to biomass from one trophic level to the next! The Food Chain : The answer has to do with trophic levels,
As you probably know, the organisms at the base of the food chain are photosynthetic; plants on land and phytoplankton (algae) in the oceans. These organisms are called the producers, and they get their energy directly from sunlight and inorganic nutrients.
- The organisms that eat the producers are the primary consumers.
- They tend to be small in size and there are many of them.
- The primary consumers are herbivores (vegetarians).
- The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers.
- The secondary consumers tend to be larger and fewer in number.
This continues on, all the way up to the top of the food chain. About 50% of the energy (possibly as much as 90%) in food is lost at each trophic level when an organism is eaten, so it is less efficient to be a higher order consumer than a primary consumer.
- Therefore, the energy transfer from one trophic level to the next, up the food chain, is like a pyramid; wider at the base and narrower at the top.
- Because of this inefficiency, there is only enough food for a few top level consumers, but there is lots of food for herbivores lower down on the food chain.
There are fewer consumers than producers. Land and aquatic energy pyramids
|Trophic Level||Desert Biome||Grassland Biome||Pond Biome||Ocean Biome|
|Primary Consumer (Herbivore)||Butterfly||Grasshopper||Insect Larva||Zooplankton|
|Secondary Consumer (Carnivore)||Lizard||Mouse||Minnow||Fish|
|Tertiary Consumer (Carnivore)||Snake||Snake||Frog||Seal|
|Quaternary Consumer (Carnivore)||Roadrunner||Hawk||Raccoon||Shark|
Food Web : At each trophic level, there may be many more species than indicated in the table above. Food webs can be very complex. Food availability may vary seasonally or by time of day. An organism like a mouse might play two roles, eating insects on occasion (making it a secondary consumer), but also dining directly on plants (making it a primary consumer). image source: http://iqa.evergreenps.org/science/biology/ecosystem_files/food-web.jpg Keystone Species : In some food webs, there is one critical ” keystone species ” upon which the entire system depends. In the same way that an arch collapses when the keystone is removed, an entire food chain can collapse if there is a decline in a keystone species.
- Often, the keystone species is a predator that keeps the herbivores in check, and prevents them from overconsuming the plants, leading to a massive die off.
- When we remove top predators like grizzly bears, orca whales, or wolves, for example, there is evidence that it affects not just the prey species, but even the physical environment.
Apex Predators : These species are at the top of the food chain and the healthy adults have no natural predators. The young and old may in some cases be preyed upon, but they typically succumb to disease, hunger, the effects of aging, or some combination of them.
The also suffer from competition with humans, who often eliminate the top predators in order to have exclusive access to the prey species, or through habitat destruction, which is an indirect form of competition. Decomposers : When organisms die, they are sometimes eaten by scavengers but the remaining tissues are broken down by fungi and bacteria.
In this way, the nutrients that were part of the body are returned to the bottom of the trophic pyramid. Bioaccumulation : In addition to being less energy efficient, eating higher up the food chain has its risks. Pesticides and heavy metals like mercury, arsenic, and lead tend to be consumed in small quantities by the primary consumers.
These toxins get stored in the fats of the animal. When this animal is eaten by a secondary consumer, these toxins become more concentrated because secondary consumers eat lots of primary consumers, and often live longer too. Swordfish and tuna are near the top of the aquatic food chain and, when we eat them, we are consuming all of the toxins that they have accumulated over a lifetime.
For this reason, pregnant women are advised against eating these foods.
What are 5 examples of primary consumers?
Examples of primary consumers can include rabbits, bears, giraffes, flies, humans, horses, and cows.
How will you differentiate between and primary producer and a consumer?
Hint: Ecosystem is a system in which every single organism interacts with each other and to its surrounding, living in a particular area. It includes both biotic and abiotic. Energy flow is the most important stage in the ecosystem which moves life. The cycle of energy is based on the flow of energy through different trophic levels of the ecosystem.
|Producers are the living organisms which help to produce food from sunlight, soil and air.||Consumers are the living organisms which depend directly and indirectly on other organisms for their food.|
|Green plants are the producers who prepare food in their leaves with the help of photosynthesis. These are the main source of energy which pass on to the next trophic level.||Every consumer became a producer in other stages.|
|Every other organism is dependent on producers for their energy needs.||They don’t prepare them for food.|
|In the terrestrial ecosystem, major producers are herbaceous and woody plants whereas in an aquatic ecosystem, major producers are phytoplankton, algae and higher plants.||They are dependent on producers for their energy source.|
|They have an autotrophic mode of nutrition.||They have heterotrophic mode of nutrition.|
Note: In above we detailed the energy flow in the ecosystem where we get to know about the producers, consumers and food chain system. A simple grazing food chain: Grass $\xrightarrow $ First trophic level $\to$ Goat $\xrightarrow $ Second trophic level $\to$ Man $\xrightarrow $ Third trophic level.
How primary consumers are different from primary carnivores?
Carnivores or carnivorous animals rely on other animals for their food. The carnivorous animals are secondary consumers because: They feed upon the primary consumers or herbivorous animals. Herbivorous animals eat plants so they consume the energy directly from the producers.
