Answer 1

The only heterotrophs required in an ecosystem are decomposers.

Explanation:

Decomposers, such as bacteria and fungi, play a vital role in breaking down dead organic matter and recycling nutrients back into the ecosystem. They ensure continuous nutrient cycling and maintain ecosystem stability by converting complex organic substances into simpler inorganic forms that producers can reuse. Without decomposers, the ecosystem would accumulate waste, and nutrients would be locked in dead matter, halting the flow of energy and matter.
