If sleep is a way to preserve energy, we would expect
A) larger animals to sleep more, due to their high metabolic rates.
B) smaller animals to sleep more, due to their high metabolic rates.
C) hibernation to be accompanied by increased body temperature.
D) animals with smaller appetites to sleep more.

Question

Quizplus · Accepted Answer

Smaller animals tend to have higher metabolic rates compared to their body size, which means they expend energy more quickly and may require more sleep to conserve energy. This contrasts with larger animals, which generally have lower metabolic rates and may not need as much sleep for energy conservation. Hibernation typically involves a decrease in body temperature to save energy, not an increase. Appetite size is not directly correlated with sleep need for energy preservation in the context of metabolic rates.
