About the course

Decomposers break down all dead organisms and animal waste to return nutrients back to the environment. Learn about this small but vital part of the energy cycle that returns unused energy to producers. Round out your understanding of the Trophic Pyramid!

Understand energy flow by examining every part of the food chain from decomposers and consumers to producers.
