Where do plants and animals get their energy from? Explore food chains and see how energy is passed from the sun to plants and on to first, second and third order consumers.

Producers, Consumers, and Decomposers explains the roles of producers, consumers, and decomposers within an ecosystem.

This video covers:

- The idea that trophic levels are just the different levels of a food
