Biological the sequence of biological events or functions that are repeated in the same order and with the same interval. These physiological systems enable organisms to live in harmony with the rhythms of nature such as rise and fall of the tides, cycles of day and night and date offseason even. Due to this reason, biological clocks are also called as environmental rhythms. Biological clocks generate and control biological Rhythm without being influenced by external factors.
