What is a ethotherm?

Answer 1

An ectotherm is an organism that relies on external environmental conditions to regulate its body temperature. Unlike endotherms, which generate heat internally to maintain a constant body temperature, ectotherms often adjust their behavior, such as basking in the sun or seeking shade, to manage their thermal state. Common examples of ectotherms include reptiles, amphibians, and most fish. Their metabolic rates can vary significantly with changes in temperature, impacting their activity levels and physiological processes.
