Animals that maintain their core temperature through internal metabolic activity are known as
A) endotherms.
B) ectotherms.
C) mesotherms.
D) cold-blooded animals.

Question

Quizplus · Accepted Answer

Endotherms are animals that use internal metabolic activity to maintain their core temperature, whereas ectotherms rely on external sources of heat to regulate their body temperature. Mesotherms have traits of both endotherms and ectotherms and are not a commonly used term in biology. "Cold-blooded animals" is not a scientific term and can refer to both endotherms and ectotherms, so it is not a suitable answer.
