Sleep and wake cycles
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.

The word that best fits the definition is "circadian." Circadian rhythms are internal biological processes that follow a roughly 24-hour cycle, influencing behaviors such as sleep and feeding patterns, which determine whether an animal is nocturnal (active at night) or diurnal (active during the day).
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.

A biological rhythm refers to the cyclical patterns or regular oscillations in biological processes, such as sleep-wake cycles, body temperature fluctuations, and hormone release, that occur in living organisms. These rhythms are influenced by internal biological clocks, external cues like light/dark cycles (circadian rhythms), and periodicity in daily, monthly, or seasonal cycles.
Animal testing constantly changes. It is closely regulated in many countries.
Internal control of natural cycles refers to the way in which organisms regulate their biological processes, such as growth or reproduction, without external influences. This control is often achieved through internal mechanisms such as hormones or circadian rhythms. It allows organisms to adapt to environmental changes and maintain homeostasis.
A change in body temperature over the course of a day alone does not definitively prove that an animal is an ectotherm. While ectotherms typically have body temperatures that fluctuate with environmental conditions, endotherms can also exhibit daily temperature variations due to factors like activity levels and circadian rhythms. To determine if an animal is an ectotherm, one would need to consider its thermoregulatory mechanisms and how it maintains body temperature relative to its environment.
