Question

Give an example of an endothermic animal.

Answer 1

Hint: Endothermic organisms can regulate their body temperature which remains constant irrespective of their surroundings. The exhibit homeostasis.

Complete answer:
Temperature is the most economically relevant environmental factor. The average temperature on land raises seasonally, decreases progressively from the equator towards the pole and plans towards the mountain top. Temperature plays an important role in both, latitudinal and altitudinal distribution of organisms. Temperature significantly affects the enzyme kinetics and basal metabolism as well as activity and other physiological functions of an organism.
Based on thermoregulation and homeostasis, organisms are classified into two groups, ectotherms, and endotherms.
Endotherms are the organisms that regulate their body temperature which remains constant irrespective of their surroundings. They are also known as warm- blooded animals or homeotherms. The endotherms primarily include the birds and the mammals. For example, polar bears, lions, human beings, etc.
If the heat loss exceeds the heat generation, metabolism increases to make up the loss. Thus, the animal shivers to raise its body temperature. If heat generation exceeds the heat loss, the body starts sweating or perspiring increases.

Note:- Unlike ectotherms, endotherms can live and survive at quite low temperatures. Since they are required to produce heat continuously. They require high quantities of energy. - Only birds and mammals are universally endothermic groups of animals but certain fishes like lamnid sharks, tuna, and billfishes are also endothermic. - Some ectotherms, including several fishes and reptiles, show regional endothermy, where muscle activity is increased in certain parts of the body to maintain a higher temperature than the rest of the body. This is important for better movement and the use of senses in cold environments.
