What is a habitat?
A habitat is the place where a living thing lives. It is its home.
A habitat gives a living thing what it needs: food, water, shelter and space to live.
Every living thing lives in a habitat. In Britain, habitats include woods, gardens, ponds and the seashore.

Living things suit their habitats
Most living things live in a habitat that suits them. The habitat has what they need, and their bodies fit the place.
A fish has fins and gills. It breathes in water, so it lives in a pond, a river or the sea.
A hedgehog has spines to protect it. In winter it can sleep in a pile of leaves.
A snail has a shell. It needs damp places, because its body dries out in the sun.
A worm has no legs. It moves through damp soil, and it breathes through its damp skin.

Watch out
Watch out: depend does not mean the same as eat. A tree depends on the soil, and a bird depends on the tree for a nest.
Try it at home (with a grown-up). With a grown-up, look at a tree or a hedge in the park or garden from a safe distance. Find one living thing that uses it, such as a bird, a bee or a minibeast. Do not touch wild animals or pick any plant. Wash your hands afterwards.
Exam tip
Grown-up tip. Ask: “Who needs this tree? What does the tree give them?” Let your child say one thing that depends on another living thing.
