Answer:
The correct answer is option b. "The amount of waste would build up and the toxins produced would harm the animals and humans".
Explanation:
Fungi play a significant position in the ecosystem as decomposers and reuseable. When fungi consume the waste they encourage those other organisms to consume elements such as phosphorus and nitrogen from decomposing matter.
If a dominant fungicide would kill almost all fungi, the amount of scrap would strengthen up and the toxins constructed would injure the humans and animals.
