Question

Describe how, and at what levels, decomposers operate within an ecosystem that has 4 trophic levels - producers, primary consumers, secondary consumers, and tertiary consumers.

Provide examples of the role of decomposers on at least two of those levels.

Two roles of decomposers are:
•Restoring nutrients in the soil
•Providing nutrients to plants
