Biological rhythms in non-chordates, which encompass a vast array of invertebrate species, are essential for their survival, adaptation, and reproductive success. These rhythms are recurrent, cyclical patterns of physiological and behavioral activities that synchronize with environmental cues, such as light-dark cycles, temperature changes, and tidal rhythms. The study of biological rhythms in non-chordates provides insights into how these organisms optimize their activities in response to environmental changes.

1. Circadian Rhythms:
   One of the most prominent biological rhythms in non-chordates is the circadian rhythm. Circadian rhythms are approximately 24-hour cycles that regulate various physiological processes. In many invertebrates, these rhythms are entrained by external cues like light and temperature. The internal circadian clock, often located in neural structures, helps non-chordates anticipate and adapt to daily environmental changes. For ____ __________ _________ ____ ____ _____.
