Ch. 3 Lesson 3: Producers, Consumers, and Decomposers


Producers are any kind of green plant. Green plants make their own food by taking sunlight and using the energy to make sugar. The plant uses this sugar, also called glucose to make many things, such as wood, leaves, roots and bark. Trees, such as Pine and Eucalyptus are examples of producers.

Consumers have to feed on producers or other consumers to survive. Deer are herbivores, which means they they only eat plants (producers). Bears are another example of consumers. Black bears are omnivores and scavengers, like skunks and raccoons, which means they they will eat just about anything. In a forest community, Black Bears will eat blueberries, bugs, acorns, and many kinds of nuts.

Decomposers are the garbage men of the animal kingdom; they take all the dead animals and plants (consumers and decomposers) and break them down into their nutrient components so that plants can use them to make more food. Decomposers in the forst come in many different shapes and sizes. Shelf fungus is a fungus that grows on the sides of trees. It grows into the tree and decomposes it slowly. Have you ever been walking through the woodsand come across a dead log that falls apart and is full of dirt? That is because decomposers have been eating and digesting that log for several years, turing it into dirt that is wonderful for plants.
