A habitat is the place where a plant or animal lives. All living things have adaptations that help them survive in their habitats. For example, plants and animals can only live in habitats that meet their needs.
An ecosystem is a group of animals and plants and their physical environment. Coral reefs are underwater ecosystems. Coral reefs are made from skeletons of tiny creatures. Deserts are also ecosystems and they get dry weather and very little rain.
