Food Chains and Food Webs

Students learn how matter and energy flow in a food chain. They recognize that producers, herbivores, carnivores, omnivores, and decomposers are part of food chains and food webs. They extend the basic food chain in their terrariums by suggesting additional herbivores and carnivores to develop possible food webs.
