Question

How are fungi useful to science?

Answer 1

Well, they are decomposers.

Explanation:

For science, they can be researched, and some might think of cooking and eating them for nutritional benefits or to make medicines, pharmaceuticals, or whatever.

In the environment, they are important to ecosystems, as they decompose dead animals and other organisms, and then put back useful nutrients into the soil for new organisms and plants in the ecosystem to use to grow and live successfully.
