Why is fungi's role as biodegraders so important to ecosystems? a. it keeps the level of prey animals down so they do not overwhelm the ecosystem. b. it provides nutrients and oxygen to the ecosystem. c. it protects plants from harmful viruses and bacteria. d. it recycles and reuses organic molecules so they are not wasted.

D.It recycles and reuses organic molecules so they are not wasted.

Explanation:

Most of the fungi are decomposer so they gain their nutrition from dead and decaying matters. They release hydrolytic enzymes that help in the break down of dead organic matters of plants and animals and release the nutrition from them.

So they replenish and recycle the nutrient in the environment. They also protect the environment from pollution by degrading these dead organic matters. Therefore these organic matter are not wasted. Many fungi also live in symbiotic associations with algae and plants and help in their survival.

So the correct answer is D.It recycles and reuses organic molecules so they are not wasted.
