Here is a diagram of a fungus growing on a log.

A. What does the mushroom produce and what function does that have?

B. Describe how the mycelium extracts nutrients from the wood.

C. Describe the important ecological role of fungi.

(1) Mushrooms are a reproductive structure used by many types of fungi. The cell sends out hyphaes to assist in the production and selection of food. (2) The hyphae secrete wood or other material through rotting enzymes. These enzymes are separated into smaller units like monomers by biological polymers. (3) Fungi are heterotrophic, they use complex organic compounds as sources of energy and carbon.
