what decomposers often live on a log

Decomposers that often live on a log include a variety of fungi, bacteria, and small invertebrates. Common decomposers found on or in a rotting log are fungi (such as mushrooms, molds, and mildew), bacteria, earthworms, termites, woodlice (isopods), millipedes, beetles and their larvae, snails, slugs, and ants. These organisms break down the organic matter in the log, recycling nutrients back into the soil. Fungi play a primary role by secreting enzymes that decompose lignin and cellulose, the main components of wood. Small invertebrates like beetles, termites, and millipedes feed on the softened wood and fungal material. Even lichens and mosses can live on the log surface, contributing to the decomposition process. This combination creates a microhabitat full of decomposers that feed on dead wood and help recycle nutrients in forest ecosystems.
