What are the ways by which organisms respond to abiotic factors ?

Explanation

There are various ways by which organisms respond to abiotic factors. They are regulate, conform, migrate and suspend.
(i) Regulate : Some organisms are able to regulate homeostasis by physiological means they maintain constant body temperature and ionic/osmotic balance. Eg : Birds, mammals, a few lower vertebrates and invertebrate species.
(ii) Conform : The animals which cannot maintain constant internal environment confirm with external. Their body temperature changes with ambient temperature. In aquatic organisms the osmotic concentration of body fluid change with change in osmotic concentration of environment. Such animals are known as conformers. Eg : Fishes and aquatic invertebrates.
(iii) Migrate : Some animals move to safe habitat temporarily from stressful habitat and return to original habitat when the condition become favourable. Eg : Migratory birds.
(iv) Suspend : If an organism is not able to migrate, it may avoid stress by becoming inactive. It is seen in hibernation (winter sleep) Eg : bears and Aestrivation (Summer sleep) Eg : Snail.
