What term describes animals that primarily feed on other animals?

The term that describes animals that primarily feed on other animals is "carnivorous." Carnivorous animals have adaptations that enable them to hunt, catch, and consume other animals as their main source of nutrition. This includes a variety of dietary strategies, such as predation, scavenging, or parasitism, depending on the specific species.

For example, predators like lions and wolves actively hunt other animals, while scavengers such as vultures feed on the remains of dead animals. These adaptations often include sharp teeth for tearing flesh, strong muscles for chasing down prey, and keen senses that help in locating food. Understanding the carnivorous diet is essential in the study of ecological interactions, food webs, and how energy flows through ecosystems.

In contrast, other terms like "herbivorous" refer to animals that primarily consume plants, "omnivore" describes those that eat both plants and animals, and "viviparous" refers to modes of reproduction rather than dietary habits, indicating organisms that give birth to live young rather than laying eggs.
