Question
How does temperature affect the organisms?

Answer

Physiological functions as well as geographical distribution of plans and animals are governed by the temperature conditions and their thermal tolerance. Organisms which can tolerate and thrive in a wide range of temperatures are called eurythermal, e.g. most mammals and birds while organisms which can tolerate a narrow range of temperatures are called stenothermal, e.g. polar bear, amphibians.
