We know all animals have different types of teeth because of what they eat and animals are put into categories based on their diets.

Carnivores, like lions and tigers, only eat meat. So they need long and sharp canine teeth, but not molars.

Herbivores, likes cows and sheep, only eat plants. They do not have upper incisors because they cut the plants with their lips instead. But each herbivore needs their molars for grinding the mouthfuls of food.

Omnivores, like people, eat both meat and plants. We have teeth that are used for a lot of different foods.

Insectivores, like ant eaters, only eat insects. They have teeth that are square with sharp points.
