Objective: KWBAT explain how decomposers help plants grow.

The Forest Ecosystem

The grass is consumed by the rabbit, which is a consumer and needs to eat something to obtain its energy. The rabbit is then eaten by a coyote, also a consumer. When the coyote, rabbit, and grass dies, it is eaten and decomposed by worms and bacteria, which are decomposers, returning its nutrients into the food chain to be used again.
