Food chains

A food chain is a sequence describing how different animals eat each other, showing the order in which living things depend on each other for food starting with a plant and ending with an animal. The arrows in a food chain show the way in which energy is moving.

These are two examples of food chains

The initial source of energy for all food chains is the sun. A food chain always starts with a producer, usually a green plant. A producer is a plant that makes its own food from sunlight. Next a consumer that eats the producer. A consumer is a living thing that eats other plants and animals. In the first food chain the tree is the producer. The deer and the lion are the consumers. In the second food chain the flower is the producer. The flies, frog, snake and eagle are the consumers.
