Why do some fungi grow inside wood?
Quick Answer
Wood-decay fungi feed on compounds in dead or weakened wood. They break down lignin and cellulose, recycling nutrients back into ecosystems.
The Full Story
Wood is hard to digest because it is built from cellulose, hemicellulose, and lignin. Certain fungi have enzymes that let them decompose these materials, which is why they are crucial recyclers in forests. White-rot fungi can break down lignin, while brown-rot fungi mainly attack cellulose and leave wood darker and crumbly. Without these fungi, dead trees and fallen branches would pile up and nutrients would stay locked away. Their decomposition work is one reason forests continually renew their soil.
