How does an ecosystem work?

An ecosystem is a bit like a canteen where living things eat. Every ecosystem works in the same way. 1) The plants use sunlight, water, and nutrients from the soil to produce their own food. (So they are called producers).

2) The animals feed on the plants, or each other. (So they're called consumers). There are following types of consumers:

• Herbivores—which feed on plants e.g. rabbit, insect.

• Carnivores—which feed on other animals e.g. fox, lion, shark.

• Omnivores—which feed on both plants and animals e.g. humans, rats, many birds.

• Detritivores—which feed on dead organisms e.g., earth worm, crab. ants.

3) Fungi and bacteria feed on dead and waste material, and make things break down or rot. (So they're called decomposers). They recycle nutrients that the plants can use again. Without plants, all other living things would die.
