Supplement

Habitat is generally regarded as the place where an organism or a population lives, resides, or thrives. It is where the species will attempt to be as adaptive as possible to that particular environment. In ecology, a habitat would pertain to the environment where a species derives its food, shelter, and mate for reproduction. It can be a geographical area or a part of another organism. In parasitology, a habitat is the part of the host where the parasite lives. For example, the habitat of the parasite, Ascaris lumbricoides, would be the intestine of its host.

In terms of geographical areas, the habitat of an organism or a population may be classified as polar, temperate, subtropical, or tropical. It may also be typified as terrestrial or aquatic. Examples of terrestrial habitats are forest, grassland, steppe, desert, etc. Aquatic habitats include freshwater, marine water, and brackish water.


Word origin: from Latin, it dwells, third person sing. present of habitāre, to dwell
