Quizplus · Accepted Answer

The sleep-wake cycle is one of the most well-known circadian rhythms in animals, including humans. It is regulated by the timing of the release of certain hormones such as melatonin, which is under the control of the circadian clock. While other behaviors such as storage of body fat or mating may be influenced by circadian rhythms, they are not as consistently controlled by a circadian rhythm as sleep. Migration can also be influenced by circadian rhythms, but this is not true for all animals as some use other cues such as celestial navigation.
