The cause of the rooster's morning chirping.

The existence of a biological clock in the rooster's body is determined by the temporal structure of the biological clock. The chicken's eyes are very sensitive to light, and when the light comes before dawn, the faint light is perceived by the rooster, as if receiving a signal, making the rooster extremely excited, and the instinct will crow. The rooster chirping is also a warning to its territory, thus avoiding conflict.
