What is a source of food for a mushroom?

Mushrooms obtain their food primarily through a process called decomposition, where they break down organic matter such as dead plants, leaves, and wood. They secrete enzymes that digest complex organic materials into simpler compounds, which they then absorb. Some mushrooms form symbiotic relationships with plants, exchanging nutrients with their roots in a partnership known as mycorrhiza. Additionally, some species are parasitic, deriving nutrients from living hosts.
