A habitat is the area in which an organism lives. It is a summary term for all the resources, physical and living which are present in an area. It is the natural environment in which an organism lives, and the physical environment which surrounds a population.
Animal habitats[change | change source]
Most animals live in one type of environment because they are best suited to it. We say they are 'adapted to this environment'. For example, animals such as frogs, newts, and ducks have webbed feet to help them swim in the water. There are many different types of habitats and many kinds of adaptations to each habitat.
If the habitat changes, it may no longer be suitable for the animals and plants that live there. Climate change is making some habitats warmer, and so many animal species are moving to cooler areas. However some species are not able to move and the populations are getting smaller. Scientists think that 10% of species may become extinct because of these changes. Other habitats have been cleared to make them into farm land. In Australia for example, 80% of the eucalypt forests have been cleared for farming over the last 210 years. This is threatening the survival of forest animals such as the koala.
Plant habitats[change | change source]
Just as animals adapt to the places they live, so do plants. Plants are adapted to a wide variety of habitats. As a result, each plant has certain characteristics. Some are adapted to living on land while others live in water. Plants that grow on land usually have stiff stems to hold them upright, while water plants tend to have less rigid stems because the water supports them.
Plants that live in dry climates like the desert have few or no leaves. Many, such as cacti, store water when rain occurs. Their adaptations save water. Plants that grow in shaded areas have large leaves to capture as much sunlight as possible, or they climb towards the light.
