Detailed explanation-1: -“Cold-blooded” does NOT mean that these animals have cold blood. “Warm-blooded” means that the animal’s nervous system automatically controls its body temperature regardless of environmental conditions. Another word for “warm-blooded” is endothermic-birds and mammals are endotherms.

Detailed explanation-2: -Warm-blooded animals have a much stronger immune system to defend against such microorganisms. They gain energy in the form of heat to regulate body temperature for survival. They can easily produce heat within their body. Cold-blooded animals cannot survive in any extreme temperature and conditions.

Detailed explanation-3: -Cold-blooded animals do not maintain a constant body temperature. They get their heat from the outside environment, so their body temperature fluctuates, based on external temperatures. If it is 50 °F outside, their body temperature will eventually drop to 50 °F, as well.
