A habitat is a place where a collection of plants and animals live and which provides them with food and shelter. Seashores, gardens and ponds are all examples of habitats. Habitats can be big (a jungle, for example) or small (a leaf, for example).
The animals and plants living in a woodland habitat, for example, might include owls, thrushes, caterpillars and oak trees.
The animals and plants in one habitat are suited to live there and may not be able to survive in other habitats. A woodland owl, for example, would not survive in a desert habitat.
When a habitat changes, the animals and plants that live there are affected. For example, when pond weed is removed from a pond, the fish and snails that rely on the pond weed for food may find it hard to survive.
