A FOOD CHAIN
What is a food chain?
All living things needs food to survive.
A food chain shows how each living thing gets food, and how nutrients and energy passes on from creature to creature, or from environment to creature. Below is a basic example of a food chain.
The elements of a food chain
The SUN is usually the beginning of most food chains.
Nearly all of the energy used by living things on earth to survive originally came from the sun.
PRODUCERS, which are plants, produce their own food from sun, water, air (carbon dioxide), and soil.
CONSUMERS, which are usually animals, consume other plants and animals.
An HERBIVORE only eats plants.
A CARNIVORE only eats meat.
An OMNIVORE eats both plants and animals.
DECOMPOSERS, which include fungi, bacteria, and worms, eat decaying plants and animals, and decompose them back into soil. The soil can then be used by plants to grow.

Many FOOD CHAINS make up a FOOD WEB.
