👉 Diurnalness refers to the phenomenon of animals or plants having regular, predictable activities during the day. It involves a cycle of activity that repeats every 24 hours, from sunrise until sunset. This cycle is often described by the concept of "day and night," with some species waking up earlier in the morning and others sleeping later into the evening. Diurnalness helps to maintain ecological balance as animals need to feed and rest during the day when food availability is limited or scarce.
