Why are mushrooms important to the food chain?

They are nutritious and one of the smallest food supply, which starts the chain. It also is the end of the chain, wher it grows where life decomposes.

We eat fungi, such as mushrooms ... Decomposers like fungi and bacteria complete the food chain. They turn organic wastes, such as decaying plants, into inorganic materials, such as nutrient-rich soil. Decomposers complete the cycle of life, returning nutrients to the soil or oceans for use by autotrophs.
