Organisms are divided into two major groups as per the maintenance of their body temperature. In simple words, they are termed as cold-blooded animals like reptiles and warm-blooded animals like most mammals including humans.
Warm-blooded animals are those, who can maintain their body temperatures constant irrespective of the environment or climate outside. Humans maintain their body temperature at 37oC or 98.6 oF. These animals use the heat energy generated by their metabolism to do so. Hence humans can adapt to live in diverse environments from Tundra to tropics to temperate regions. Such animals are called Endothermic.
Cold-blooded animals can not have a constant body temperature and they constantly search for a comfortable temperature environment as their body temperature changes along with the temperature of the surroundings. On hot days they search for cool shades to survive and on cold days they like to huddle up and keep warm in some cozy place. Such animals are called Ectothermic.
Heterothermy is a phenomenon seen usually in some animals with high metabolic rates, especially small mammals. These animals can change their body temperature for a certain amount of time. Thus when there is low activity, they can cool down their body and lie dormant. Example - Bats.
Homeothermy is where the internal body temperature is maintained constant, like humans, irrespective of surroundings.
