Final answer:

Animals exposed to unnatural constant illumination will likely experience a disruption of their circadian rhythms, which can have various negative health effects.

Step-by-step explanation:

Circadian rhythms are the daily cycles of behavior and physiological processes that enable living creatures to adapt to the 24-hour day/night cycle. Light is a critical environmental cue that helps align our biological clocks with the day and night. Continuous exposure to light can interrupt these rhythms, as it impedes the natural cycle of light and darkness that is required for healthy sleep and wake cycles. This disruption can lead to problems like insomnia, anxiety, and depression. Moreover, it has been observed in early studies that interruption of the dark period, rather than the light period, can alter animal behavior, further establishing the importance of a natural light-dark cycle for circadian rhythm regulation.
