Question

How do ectothermic organisms regulate their body temperature?

Answer 1

Most animals need to maintain theircore body temperature within a relatively narrow range. Endotherms use internally generated heat tomaintain body temperature. ...Ectotherms depend mainly on external heat sources, and their body temperature changes with thetemperature of the environment.

Answer 2

ANSWER

Endotherms, such as birds and mammals, use metabolic heat to maintain a stable internal temperature, often one different from the environment. Ectotherms, like lizards and snakes, do not use metabolic heat to maintain their body temperature but take on the temperature of the environment.
