Explanation

Lunar rhythms in biological systems are phenomena whose timing corresponds to a lunar month, the Moon's (roughly) 29.5 day orbit around Earth. In some cases these rhythms may depend on external cues, such as a greater or smaller amount of moonlight due to the moon's phases. In other cases, for example, the approximately-monthly cycle of menstruation, the correlation in timing may reflect no known lunar influenceA circadian rhythm is any biological process that displays an endogenous, entrainable oscillation of about 24 hours. These rhythms are driven by a circadian clock, and rhythms have been widely observed in plants, animals, fungi and cyanobacteria. The term circadian comes from the Latin circa, meaning around (or approximately), and diem or dies, meaning day.Tidal rhythm commonly observed in marine life, which follow the roughly 12.4-hour transition from high to low tide and back.Annual rhythm is the repetitions of functions every year. For example, reproduction in animals.
