Circadian Rhythm

Circadian rhythm is a biological process that displays a pattern of biological actions over the course of roughly 24 hours. All types of organisms display a circadian rhythm, including plants and animals. In animals, circadian rhythm is the animals sleep schedule. When it gets dark out the animal will get sleepy, and when the sun comes up the animal will feel energized. In plants, circadian rhythm is the plant’s orientation. Plants will reposition themselves at different times of the day in order to maximize photosynthetic output.
