Question

(5.02 MC)Some bacteria are decomposers, which fill an important role in the food web. What would happen to an ecosystem without

decomposers?
O All levels of the food web would be affected because it would be difficult to recover nutrients from dead matter and waste.
O Primary producers would increase because of the excess nutrients available.
O Consumers would be most affected because decomposers are the main source of energy entering the food web.
O Autotrophs would take over the role of decomposers.

Answer 1

Answer: All levels of the food web would be affected because it would be difficult to recover nutrients from dead matter and waste.

Explanation: Without decomposers, dead leaves, dead insects, and dead animals would pile up everywhere. Imagine what the world would look like! More importantly, decomposers make vital nutrients available to an ecosystem's primary producers—usually plants and algae.
