Detailed explanation-1: -Ectotherms depend mainly on external heat sources, and their body temperature changes with the temperature of the environment. Animals exchange heat with their environment through radiation, conduction-sometimes aided by convection-and evaporation.
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: -For these animals, heat comes from outside (ecto-) their bodies-their environment provides their warmth. That means they require less food, and are consequently able to inhabit places that would be off-limits to endotherms. However, their activity level is limited by the surrounding conditions.
