Herbivores are animals that get their energy and nutrients solely from plants. They include:
* Grazers: Animals that eat grasses, such as cows, sheep, and horses.
* Browsers: Animals that eat leaves, twigs, and other woody vegetation, such as deer, giraffes, and goats.
* Frugivores: Animals that eat mainly fruit, such as monkeys, bats, and birds.
* Granivores: Animals that eat seeds, such as squirrels, mice, and birds.
Animals that eat both plants and animals are called omnivores, and include humans, bears, pigs, and raccoons.
