What is the role of fungi in decomposition?

Fungi play a crucial role in decomposition by breaking down complex organic materials, especially tough substances like cellulose and lignin found in plant cell walls. They are among the most efficient decomposers in ecosystems.

Fungi release enzymes onto dead organic matter and digest it externally. This process allows them to convert complex compounds into simpler substances such as nutrients, which are then absorbed by plants from the soil.

They are particularly important in decomposing dead plants, wood, and leaf litter, where bacteria alone may not be effective. Common examples include mushrooms, molds, and yeast.

By decomposing organic matter and releasing essential nutrients back into the environment, fungi help maintain soil fertility and support the continuous cycle of life.
