Question

What are poikilothermic animals?

Answer 1

Hint:Animals are multicellular organisms that are part of Animalia kingdom. Thermoregulation is the ability of an organism to keep its body temperature within some boundaries. Some animals change their body temperature according to the environment.

Complete answer:
>The poikilothermic animals are the ones whose internal temperature changes according to the environment.
>The poikilothermic animals include some fish, amphibians.
>The poikilotherms are the group of organisms that do not have mechanisms to regulate temperature of the internal environment.
>Poikilotherms are also called cold blooded animals.
>The body temperature of poikilotherms is variable.
>Some examples of poikilotherms are fish, reptiles and amphibians and sloth.
>Poikilotherms get heat from the environment and are called ectothermic animals.
>Poikilotherms are opposite of the homeotherm.
>The homeotherms maintain the thermal homeostasis.
>The total energy requirement of the poikilotherms is low because they do not use their metabolism to cool or heat themselves.
>The homeotherms are called warm blooded animals.
>The homeotherms have relatively constant body temperature,

Note:The poikilotherms can use more energy to grow and reproduce. They can colonize areas of limited food and water because they expand no energy in maintaining the body temperature. Lizard is also a poikilothermic animal. The poikilothermic are the ones that cannot produce heat in their own body. They have to depend on the environment to keep themselves warm. The reptiles often bask in sun to get warm.
