Question

Why are mushrooms important to the food chain?

Answer 1

In an ecosystem, fungi play the role of decomposers -- they break down dead organic matter and return vital nutrients to the soil. Without fungi, nutrients would not cycle through an ecosystem, causing the breakdown of the entire food chain

Answer 2

Mushrooms are important to the food chain as they recycle nutrients into the eco-system and prepare food for animals.  

EXPLANATION:

Mushrooms are basically fungi. In an ecosystem, fungi are decomposers that break down the organic dead. The decomposition of the organic dead helps to return vital nutrients to the soil.

The decomposition also helps the animals to get food. If the mushrooms will not decompose the organic dead, the vital nutrients will not get recycled into the ecosystem which will eventually break the food chain.
