Quizplus · Accepted Answer

Ectotherms are animals whose body temperature varies with the environmental temperature. They rely on behavior and external conditions to regulate their body temperature. Thermophiles thrive in high-temperature environments, mesophiles prefer moderate temperatures, and amniotes are a group of animals characterized by their ability to lay eggs that are protected by membranes, but none of these terms refer specifically to an animal whose body temperature fluctuates with the external environment. Endotherms, on the other hand, are animals that maintain a constant internal body temperature regardless of the external environment, such as birds and mammals.
