What is a food web?

A food web is a diagram that shows how different food chains in a habitat are linked.

A food chain shows one feeding pathway, but a food web shows many linked food chains in the same ecosystem.

Each arrow points from the food to the feeder and shows the direction of energy transfer.

A producer is a plant or alga that makes its own food by photosynthesis and is at the start of many food chains.

A consumer is an animal that eats other organisms, such as plants or other animals.

A primary consumer is an animal that eats producers, and it is usually a herbivore.

A top predator is an animal that has no predators of its own in that food web.

A predator is an animal that hunts and eats other animals, and the animals it eats are its prey.

An omnivore is an animal that eats both plants and other animals.

Other populations can rise or fall because they lose a food source or a predator, which changes the balance of the food web.
