• Why are decomposers an essential part of a healthy ecosystem? • • A. Decomposers are a necessary part of the diet of most

consumers. • B.Decomposers convert plant material into a form that primary

consumers can use.• Decomposers make resources available to producers by

breaking down waste materials. • • Decomposers extract energy from sunlight as they break down

plant materials, adding returning energy to the system.

• During the 1930s, a large region of the Great Plains experienced a drought that turned grasslands into dust. How did this change most likely affect populations of insects living among the grasslands?

environment.• • D.They were not affected because the size of a population cannot change

over time.
