This document discusses producers, consumers, and decomposers in an ecosystem. Producers are living things that make their own food through photosynthesis, consumers eat other living things, and decomposers break down the remains of dead organisms and turn them into nutrients. A food chain is made up of at least one producer, one consumer, and one decomposer transferring energy as they consume each other. The document then provides examples of producers, consumers, and decomposers and signals there will be a review of terms, questions to test understanding, and a game to dramatize a food chain.
