- The food web would be incomplete without organisms that decompose organic matter. Some elements, such as nitrogen and phosphorus, are required in large quantities by biological systems; yet, they are not abundant in the environment. The action of fungi releases these elements from decaying matter, making them available to other living organisms.

NARRATOR: Fungi can be found in many forms in our everyday lives—the yeast that causes bread to rise, the mold that grows on bread, the mildew found in a shower, as well as the mushrooms that adorn the top of a pizza.
Mushrooms are perhaps the most recognizable type of fungi. The top of a mushroom is made up of a cap, which is supported by a stemlike structure called the stalk. These two parts meet at a ringlike structure found just beneath the cap, called the annulus. These portions of the mushroom are visible, while the bulk of the organism may be found below the surface. The underground portion of the mushroom is called the mycelium. A network of threadlike fibers called hyphae make up the mycelium, which can extend for miles in some types of mushrooms.
