Question

Quizplus · Accepted Answer

Circadian cycles are daily cycles, while circannual cycles are yearly cycles, so the best choice is D. A is incorrect because light-dark cycles are specifically associated with circadian rhythms, while temperature is associated with both circadian and circannual rhythms. B is incorrect because endogenous and exogenous rhythms refer to the source of the rhythm (internal or external), rather than the duration of the cycle. C is incorrect because mating and hibernation are behaviors that may be influenced by circadian and circannual rhythms, but they do not define the cycles themselves.
