Do you know some animals eat only plants, but some just eat meat while some of them eat both? The sizes of animals have nothing to do with what they eat. Some of the largest animals only eat plants, while some very tiny animals only eat meat. By what they eat, animals are classified into three main types: herbivores, omnivores, and carnivores.
Herbivores are animals that only eat plants. Herbivores usually concentrate their munching on the seeds of plants or fruits. Their digestive tracts are special and designed to fit different plants they might eat. As a whole, herbivores have big front teeth to grasp as well as cut the plants they eat. They are often very large animals, such as elk, cow, horse, and deer, but they can also be small and medium-sized such as squirrels, chipmunks, sheep, and goats.
Carnivores are animals that only eat meat. In the wild, these animals will have to hunt other animals for their food. These animals often have sharp molars as well as big canine teeth to cut and tear up the meat. Carnivores can be large, medium, and small-sized animals, such as lions, tigers, wolves, hawks, eagles, frogs, and birds like robins and spiders.
Omnivores are animals that eat plants as well as meat. These animals can eat almost anything around them when they are hungry. They also have the benefit of getting their food at any time around the year, such as fruits and seeds of plants during the summer and meat during the other seasons. Because they can eat almost everything they find, they usually have various types of teeth. These animals can be large, medium, and small-sized animals, such as bears, raccoons, pigs, and some birds.
