The term for an animal that hunts for food is a "predator." Predators are organisms that actively seek out, kill, and consume other organisms, known as prey, to obtain sustenance. This behavior is fundamental to many ecosystems, as it helps maintain population balance and supports the food web. Predators possess various adaptations that aid in hunting, such as sharp teeth, keen eyesight, and stealthy movements. Examples of predators include lions, wolves, eagles, and certain species of fish. The predator-prey dynamic is crucial for ecological health and biodiversity, influencing the survival and evolution of both groups.
