Food Webs

A food web is a diagram to show how animals and plants are linked by how they get their food.

Plants use the sun’s energy to make food from carbon dioxide and water. These are known as producers.
Primary consumers are the animals that eat the plants.
Secondary consumers are animals that eat the primary consumers.
Tertiary consumers are carnivorous animals that eat the secondary consumers. Decomposers, like fungi and bacteria, break down dead animals and plants and return their nutrients to the soil or water.

Food webs are often simple diagrams of just some of the organisms in an ecosystem. In reality, food webs may be made up of hundreds of different animals, plants, bacteria and fungi.
