Tertiary consumers are the organisms that eat the second-level consumers. Like eagles or big fish, these are carnivores that eat other meat.

Some food chains have more steps, like when carnivores eat tertiary consumers. This is called a quaternary consumer. Apex consumers are the organisms at the top of a food chain. Learn more about food chains with this fascinating Tundra Plants and Animals teaching wiki. Or, explore food chains on the farm with these Farming Food Chain Cloze Procedure worksheets. While this poster will look wonderful displayed on your classroom wall, its versatility extends far beyond a mere classroom display! Use this food chain poster to enhance your students’ learning through whole-class analysis and discussion. Use guiding questions to explore the flow of energy through the food chain, such as:Primary consumers - Organisms that feed on the producers. Examples of these are the monkeys, macaws, tapir, butterflies, sloths and toucans. Consumers— This level of the food chain can be broken down into herbivores (who eat producers), secondary consumers (who eat herbivores), tertiary consumers (who eat secondary consumers), and predators (who eat other consumers).

The average efficiency of energy transfer between trophic levels is around 10%. Because of this inefficiency, food chains can only be so long. Each of the above groups is called a “trophic level,” and it shows how many energy and nutrient transfers, or “consumption steps,” are between an organism and the energy source that started the food chain, such as light. As we’ll see below, it’s not always easy to put organisms in the right trophic level. People are omnivores, which means they can eat both plants and animals. What is Food Web? Most food webs don’t show decomposers. You may have noticed that the food web above for Lake Ontario does not. Still, all ecosystems need ways to get rid of waste and dead things. There's a lot to cover in your food chain lesson plans, but here are a few tips to make teaching about the food chain easier — and more fun too!

There are many different kinds of animals and plants in the detritus food chain, such as algae, bacteria, fungi, protozoa, mites, insects, worms, and so on. A food web, on the other hand, is more complicated than a food chain, just as the name implies. The food web shows a connection between the various food chains in a single ecosystem. How Do You Teach the Food Chain and Food Webs? A food web is a natural interconnected food chains that represents the complex relationships between producers, consumers, and decomposers. 2. What is food chain? The length of the food chain is important because the amount of energy passed from one trophic level to the next decreases as the number of trophic levels goes up. Usually, only 10 percent of the total energy at one trophic level is passed to the next because the rest is used in the metabolic process. In most food chains, there are no more than five trophic levels. During energy transfer in the food chain, about 90% of the energy that could be used is lost. Only 10% of the energy that is available is passed on to the next level. The rest of the energy leaves the food chain in one of several ways:

Ecologists have made and tested hypotheses about the nature of ecological patterns related to food chain length. For example, they have thought that the length of a food chain increases with the size of an ecosystem, that energy decreases at each level, or that long food chains are unstable. Species in a food chain are interdependent. This interdependence helps to maintain the population of any one species in the ecosystem. The primary energy source is the green plants or producers. These plants utilize sunlight and convert it into chemical energy through photosynthesis. Herbivores feed on these plants for energy. The energy then flows through the food chain as carnivores (animals that eat other animals) consume herbivores, and so on. The food chain starts with producers and moves up through various trophic levels.

Alongside the visual depictions of these food webs are some subject-specific terminology. This key vocabulary poster supports the understanding of the other Food Web Posters. With words like “prey,” “consumers,” and “heterotroph” defined and illustrated, these posters make a great display and learning scaffold for independent learning. Post them on your science bulletin board and enjoy exploring some wonderful ecosystems. Producers: Phytoplankton, cyanobacteria, algae, and green plants are all examples of producers in a food chain. This is the first link in a chain of food. The first step in a food chain is the producers. The farmers make food by using the energy from the sun. Autotrophs are another name for producers because they make their own food. Producers are plants and other living things that make their own food through a process called photosynthesis.
