Circadian can be translated as 'about' (circa), 'daily' (dian). Almost animals I can think of (plants, too) are responsive to the daily light/dark cycle of the sun, hence 'circadian'.
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).
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 controlled by the hypothalamus in humans. Circadian rhythm refers to the body's biological clock that determines when a person should sleep, and it controls a variety of other body processes, as well.
Biological rhythms that occur on a daily basis are known as circadian rhythms. These rhythms regulate the sleep-wake cycle, hormone production, and core body temperature over a 24-hour period. They are influenced by environmental cues such as light and help maintain the body's internal clock.
example of these rhythms in both humans and animals is the circadian rhythms which occur every once a day.

Circadian rhythms
Circadian rhythms are the light-dark cycles that daily govern the rhythmic changes in the behavior of people and animals. A biological clock governs these cycles and repeated disruptions to them can cause illness.

Circadian rhythms are a living organisms day/night cycles, daylight interacting with body hormone chemistry.
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.
