A habitat is the type ofenvironment that a particular plant or animal lives in. These have adapted to the conditions within the habitat and availability of food may result in a limit to the number of creatures that live in a particular habitat. Animals and plants living in a habitat are called a community and also form part of food chain and consequently a food web. Changes in the conditions within a habitat can cause a reduction in the supply of food which may result in animal movement, adaptation or death. Habitats are often changed, not by other environmental or climatic factors but by the intervention and action of humans. As we continue to use the land and oceans we too are affecting habitats, sometimes by accident, negligence or as a consequence of a determined act.
