Plants are described as being able to make their own food during photosynthesis. Animals that eat plants are named as herbivores. Descriptions of omnivores and carnivores are also given. Food chains are explained, and specific detail is given regarding the flow of energy from producers to consumers.

Ask students to choose a particular ecosystem and study the organisms that live in it. They should put together a slide show or animation that explains the flow of energy through the chain, describing each organism in terms of producers and consumers.
