What is a predator?

A predator is defined as an animal that hunts and feeds on other animals, which is precisely why the answer indicating that it is an animal that hunts other animals is correct. Predators play a crucial role in the ecosystem by helping regulate the population of prey species, thus maintaining a balance within the food web. This hunting behavior is essential for their survival, as it provides them with the necessary nutrients to thrive.

In contrast, an animal that primarily eats plants would be classified as a herbivore, not a predator. The option referring to an animal that is hunted describes prey, which is the opposite of a predator. Lastly, the option about living in water does not define a predator, as predators can inhabit various environments, including land and air, in addition to aquatic habitats.
