The pineal gland secretes the hormone melatonin, which is involved in the control of circadian rhythms
circadian rhythms.
Daily animal behavior cycles are called circadian rhythms. These rhythms are driven by internal biological clocks and typically follow a 24-hour cycle, influencing various physiological and behavioral processes in animals.
Plants open and close at certain times of the day due to circadian rhythms and environmental cues like sunlight and temperature. Animals hibernate at certain times of the year to conserve energy during periods of food scarcity and harsh weather conditions.
The mantis shrimp has one of the most accurate internal clocks in the animal kingdom. They have been known to have precise circadian rhythms that help them with activities like hunting and mating.
Internal desynchronization refers to a disruption in the synchronization of biological rhythms within an organism. This can occur when different internal biological clocks, such as the sleep-wake cycle and the circadian rhythm, become out of sync with each other. Internal desynchronization can lead to health issues such as sleep disorders and impaired cognitive function.

Not exactly. Circadian rhythms are a subset of diurnal rhythms. Diurnal rhythms reoccur daily and can be circadian and non-circadian. Circadian rhythms can be set by the environment (entrainment), but are not dependent on environment stimulus for continuation (free-running) (ie. hormone secretion). Non-circadian rhythms are responsive to the environment, but still operate on a daily cycle (ie. the process of photosynthesis).

Circadian rhythms regulate the sleep-wake cycle, hormone secretion, and body temperature, which in turn affect cognitive function, mood, and physical performance. Disruption of circadian rhythms can lead to sleep disorders, mood disturbances, and impaired cognitive abilities. These rhythms are driven by an internal biological clock located in the brain that responds to light and darkness cues from the environment.
True. Diurnal rhythms refer to biological processes that follow a 24-hour cycle, while circadian rhythms specifically refer to the body's internal clock that regulates these processes over a 24-hour period. Therefore, diurnal rhythms are a component of circadian rhythms.

Circadian rhythms are a living organisms day/night cycles, daylight interacting with body hormone chemistry.
Biological clocks and circadian rhythms are both mechanisms that regulate physiological processes in organisms based on time. A biological clock refers to the internal timing system that can govern various cycles, including circadian rhythms, which specifically operate on a roughly 24-hour cycle. While both serve to synchronize an organism's functions with environmental cues, biological clocks can encompass a range of time scales (e.g., ultradian or infradian rhythms), while circadian rhythms are strictly tied to the day-night cycle. Ultimately, circadian rhythms are a subset of the broader category of biological clocks.
