Fungi spread through vast underground networks of thin threads that break down dead material for food.

The longer version

Thread-like filaments called hyphae branch through soil and dead matter, forming a web fine enough to penetrate tiny spaces. Their large combined surface area is what makes them effective feeders, since absorption happens across the whole network.

Dead material is broken down from outside. Enzymes are released into the surroundings and split tough compounds such as cellulose and lignin into smaller molecules that can be taken in. What the fungus does not use becomes available to other organisms, so the network also moves nutrients through the community. The same threads can link with plant roots, swapping minerals for sugars produced above ground.
