Answer 2

Correct answer is c

Because Aves and mammals are homeothermic  which is able to survive only when the internal body temperature is within a narrow range.

Poikilothermic animals have body temperature that changes with the temperature around them. They donot need to control their body heat at all time so they need much less energy. Fish, reptiles etc are fall under poikilothermic.
