Nocturnal behavior refers to the activities and habits of organisms that are primarily active during the night. Many animals, such as owls, bats, and raccoons, have adapted to this lifestyle to avoid predators and reduce competition for food. Their senses, like vision and hearing, are often enhanced to help them navigate and hunt in low-light conditions. This behavior can also be observed in some plants, which may open their flowers or release scents at night to attract pollinators like moths. Nocturnal activity plays a crucial role in various ecosystems, influencing food chains and interactions among species.
