Final answer:
Carnivores are animals that exclusively eat the tissues of other animals, with obligate carnivores depending only on meat and facultative carnivores consuming both meat and plant material.
Step-by-step explanation:
Animals that feed exclusively on the tissues of other animals are called carnivores. The term carnivore comes from the Latin words for "meat eater." Within the carnivorous group, there are obligate carnivores, such as members of the cat family like lions and cheetahs, which rely solely on animal flesh for their nutritional needs. Conversely, facultative carnivores can digest both animal and non-animal food, though they primarily consume meat. In addition, there exist animals known as scavengers, which feed on dead animals without necessarily hunting them themselves.
