Secondary consumers - Organisms or animals that feed on primary consumers. These include Iguanas and frogs. Test students’ memories by showing them the poster, then hiding it and having them tell you what they remember. This PowerPoint has pictures of animals and will help your kids to understand how the food chain works. Food chains are of two types on the basis of the primary energy source: Detritus and Grazing Food chain. Grazing Food Chain

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. This animal food chain PowerPoint is ideal to show your entire class and it has questions for them to answer together. Can they spot the missing animal from the food chain?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!

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. Food webs are more accurate pictures of how organisms eat in ecosystems because they show how many food chains are connected to each other. Decomposers — These organisms break down organic waste, turning it into soil that is then used by producers.

Trophic level refers to the sequential phases in a food chain, beginning with producers and progressing upwards to primary, secondary, and tertiary consumers. Consumers are the organisms that eat the producers. Herbivores, carnivores, and omnivores are the three types of eaters. Herbivores only eat plants, carnivores only eat animals, and omnivores can eat both plants and animals. Some animals hunt live animals to eat, while others only eat dead animals. The animals that only eat dead animals are called scavengers. 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:

Print the posters, slide them into a clear sleeve, and hang them on a ring as a reference tool for a learning center. In a forest ecosystem, plants and trees are the ones that make things. A deer eats plants, while a carnivore like a tiger eats a deer. Tertiary consumers are the organisms that eat the second-level consumers. Like eagles or big fish, these are carnivores that eat other meat.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. The food chain doesn’t show how energy moves in the best way. But the food web is able to show how energy flows because it shows how different organisms interact with each other.
