Detailed explanation-1: -On the other hand, an organism that relies on the temperature of the environment around them to regulate their internal body temperature requires much less energy. This type of organism is called an ectotherm and commonly referred to as being cold-blooded .

Detailed explanation-2: -ectotherm, any so-called cold-blooded animal-that is, any animal whose regulation of body temperature depends on external sources, such as sunlight or a heated rock surface. The ectotherms include the fishes, amphibians, reptiles, and invertebrates.

Detailed explanation-3: -Humans are endothermic organisms. This means that in contrast to the ectothermic (poikilothermic) animals such as fishes and reptiles, humans are less dependent on the external environmental temperature [6, 7].

Detailed explanation-4: -Ectotherms rely largely on external heat sources such as sunlight to achieve their optimal body temperature for various bodily activities. Accordingly, they depend on ambient conditions to reach operational body temperatures.
