Food Chains

A food chain is a sequence that shows how energy and nutrients flow from one organism to another in an ecosystem.

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

The sun is the primary source of energy for all food chains.

The arrows in a food chain represent the direction of energy flow, indicating which organism gives energy to another.

A herbivore is an animal that only eats plants.

A carnivore is an animal that only eats other animals.

A producer is an organism, like a plant, that can make its own food using sunlight.

A consumer is an organism that cannot make its own food and must eat other organisms.

Decomposers break down dead organisms and return nutrients to the soil, completing the cycle of energy flow.

Living things need energy to grow, reproduce, and carry out daily activities.
