Which of the following describes an animal that is active primarily during the daytime?

The term that describes animals that are active primarily during the daytime is "diurnal." This behavior is characterized by animals that engage in most of their activities, such as foraging, mating, and other social behaviors, when the sun is up. Diurnal animals have adapted to utilize daylight hours for hunting or gathering food and are often more visible during these times.

In contrast, crepuscular animals are active during the dawn and dusk periods, taking advantage of the transitional light conditions. Nocturnal animals are those that are primarily active during the night, relying on darkness for hunting or other behaviors. Feral refers to domesticated animals that live in the wild and does not specifically denote their activity patterns related to time of day.
