Example of a food chain of which fungi is a part?

Detritivores and decomposers

You are probably familiar with fungi as mushrooms on pizza or mold on bread. In your kitchen, fungi are just tasty ingredients or a substance that ruins your leftovers. 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.
