The log that was once alive is undergoing decomposition. After the tree dies and falls as a log, its tissues start to break down through a natural process called decomposition carried out by fungi, bacteria, and various small animals like termites, beetles, worms, and other invertebrates. These organisms feed on the dead wood and help recycle nutrients such as carbon, nitrogen, and phosphorus back into the soil. This process creates a vital habitat and food source for many organisms and supports new plant growth. The fallen log is no longer living itself but becomes an ecosystem that supports life, often called a "nurse log" because it nurtures seedlings and other life forms, offering shade, moisture, nutrients, and protection in the environment.
What Happens to the Log
- The living tissues die, then fungi and bacteria start to break down the wood's cell walls chemically.
- Invertebrates like termites, beetles, and worms physically consume and burrow through the wood.
- Over time, this decomposition turns the log into humus and minerals that enrich the soil.
- The log becomes a microhabitat providing shelter for insects, amphibians, small mammals, and other creatures.
- It also supports new plant life growth by supplying nutrients and moisture, playing an essential ecological role.
In summary, the once-living log is no longer alive but remains a critical ecological component, decomposing and supporting diverse forms of life.
