Question

Which factor decides whether the animal is cold blooded or warm blooded?

Answer 1

Animals are the multicellular eukaryotic organisms that belong to the kingdom Animalia. Animals have the characteristics like they breathe oxygen, Consume organic food material, able to move, can reproduce sexually, etc.

Complete answer:
Cold blooded animals: Cold blooded animals are also called as the poikilothermic animals. Cold blooded animals are those animals that are not able to regulate their body temperature according to the temperature of the surrounding. These animals cannot survive in the extreme temperature conditions.
Examples – reptiles, fishes, etc.

Warm blooded animals: Warm blooded animals are also called as the homeothermic animals.Warm blooded animals are those animals which can regulate their body temperature according to the change in environment or they can also maintain a constant temperature.These animals can survive in the various temperature ranges and can adapt to any kind or environment.Example – Mammals

Factor that decide that whether the animal is cold blooded or warm blooded:

The internal body temperature of any animal is the factor that is responsible to decide whether an animal is cold blooded or warm blooded.
If the internal body temperature of any animal remains constant in various ranges of the temperature of the environment then that animal is warm blood.
If the temperature of any animal changes due to the influence of external environmental temperature, then the animal is called a cold blooded animal.
Therefore, it is clear from the above discussion that the internal body temperature is the main factor which decides whether the animal is cold blooded or warm blooded.

Note: Cold blooded animals protect themselves from the severe external environmental conditions by the two ways. That are –

Hibernation – Hibernation is the resting phase of animals during the winter season. Hibernation may be from a week to many months. Example of a hibernating animal is a bear.
Aestivation – Aestivation is the resting [phase of the animals during the summer season. Example of an entertaining animal is a crocodile.
