The term for animals that primarily eat meat is "carnivores." Carnivores play a critical role in ecosystems by controlling the populations of herbivores and helping maintain a balance within food webs. They have physical adaptations such as sharp teeth and claws designed for hunting and consuming other animals. Carnivores can be classified into different categories. For instance, obligate carnivores must eat meat to survive, while facultative carnivores can also consume non-meat foods. Common examples of carnivorous animals include lions, wolves, and hawks, each adapted to hunt and thrive in their specific environments.
