A food chain shows how each living thing gets its food. A food chain always starts with plant life and end with an animal.
Plants are called producers because they are able to use light energy from the Sun to produce food ( sugar ) from carbon dioxide and water.
Animals cannot make their own food so they must eat plants or animals. They are called consumers.
Below is a simple food chain in garden.
Snail eat grass. The grass provides energy to the snail. The energy comes from the Sun. Plants use the energy from the Sun to make their own food. They are called producers.
The arrow means "it is eaten by". If the snail is eaten by a bird, the relationship is called a food chain. The snail and the bird in this food chain are called consumers because they get their food by eating plants.
