Fungi

Fungi is a group of organisms belonging to kingdom Fungi. These are eukaryotic organisms. They are saprophtic organisms, which means they drive their food and nourishment by decaying dead and decaying organisms. They cannot synthesize their own food by photosynthesis as they do not possess pigment chlorophyll like plants, which traps sunlight energy for photosynthesis. The cell wall of fungi is made up of chitin.

The organism feeding on the wooden log is fungus. They are able to degrade lignin component of the wood into simpler compound, which is used as a source of nourishment.
