A biological adaptation is an anatomical structure, physiological process or behavioral trait of an organism that has evolved over a period of time by the process of natural selection such that it increases the expected long-term reproductive success of the organism. The term adaptation is also sometimes used as a synonym for natural selection, but most biologists discourage this usage. Organisms that are adapted to their environment are able to:
obtain air, water, food and nutrients
cope with physical conditions such as temperature, light and heat
defend themselves from their natural enemies
reproduce
respond to changes around them
Adaptations enable living organisms to cope with environmental stresses and pressures. One common form of physical adaptation is acclimatization
