What are producers, consumers, and decomposers?

Vocab Break: Food Chain

The Food Chain: A food chain is the sequence of who eats whom in a biological community (an ecosystem) to obtain nutrients. A food chain shows a food relationship among plants and animals in a specific area or environment.

Parts of the Food Chain

  1. Plants (producers) use nutrients form the Earth and energy form the sun to produce their food
  2. Animals (consumers) eat plants or other animals because they cannot produce their own food, therefore they depend on producers and/or other consumers.
  3. Bacteria and Fungi (decomposers) break down the dead animals, and turn the remains into nutrients, which are released into the soil

How are plants and animals interdependent?

Vocab Break: Interdependency

Every living thing depends on every other living thing to survive. This is called interdependency.


Interdependence and Food

  • Herbivores eat plants.
  • Carnivores eat the animals that eat the plants.
  • Omnivores eat plants and animals.
  • Decomposers eat and break down the remains of dead animals. The elements that are released during this process are put back in the soil and become food for plants.
