Which of the following best describes a predator's role in an ecosystem?

A predator plays a crucial role in maintaining the balance of an ecosystem by hunting and controlling prey populations. Predators help regulate the size of prey populations, preventing them from becoming too numerous. This control is essential for the health of the ecosystem, as overpopulation of prey can lead to depletion of resources such as food and habitat. By keeping prey populations in check, predators contribute to a diverse and balanced environment, which supports a variety of species, including plants and other animals. This interdependence helps sustain the overall stability of the ecosystem, making the predator's role vital for ecological dynamics.
