If the body temperature of an endothermic homeotherm falls below the __________ temperature,the metabolic rate increases.

Question

Quizplus · Accepted Answer

The lower critical temperature is the point below which an endothermic homeotherm's metabolic rate increases to generate heat and maintain body temperature. Therefore, if the body temperature falls below this point, the metabolic rate will increase. The other options are not relevant to this situation: the upper critical temperature is the point above which metabolic heat production cannot maintain body temperature and incipient lethal temperatures refer to points beyond which the organism cannot survive.
