What is a food chain?
A food chain shows how plants and animals get their energy.
Producers and consumers
A food chain always starts with a producer. This is an organism that makes its own food. Most food chains start with a green plant, because plants can make their food by photosynthesis.
A living thing that eats other plants and animals is called a consumer.
Predators and prey
A predator is an animal that eats other animals. The animals that predators eat are called prey. Predators are found at the top of a food chain.
