Detailed explanation-1: -Ectotherm Definition. An ectotherm is an organism in which internal physiological sources of heat play a minimal or insignificant role in regulating body temperature. Such species (for example, frogs) rely on external heat sources, allowing them to function at very low metabolic rates.
Detailed explanation-2: -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.
Detailed explanation-3: -An ectotherm (reptile/amphibian) relies primarily on its external environment to regulate the temperature of its body. Endotherms (birds) are able to regulate their body temperatures by producing heat within the body.
