Answer:

The major difference between these three groups is that CARNIVORES eat meat, herbivores eat plants, and omnivores eat a little of both. Each has a different kind of teeth and digestive system that helps it eat and digest its food.

If we go a little more in depth…

Carnivors have strong, sharp teeth - MADE for tearing meat off the bone. They also only have one stomach. Their saliva doesn’t have digestive enzymes which means they barely chew their food and leave it up to the stomach to digest and extract the nutrients the animal needs. Examples - Wolves, cougars, owls and sea lions.

Herbivors only eat plans. They spend a lot of time chewing and have flat teeth that help to GRIND down the plant. Their stomachs have more than one chamber, where food is fermented for EASIER digestion. Examples - koalas, pandas, gazelles and zebras.

Omnivores eat both ANIMALS and plants. Humans are a prime example of omnivores. The digestive system of an omnivore is similar to a carnivore, however omnivores can digest plant matter easier than most herbivores. Examples - Humans, ostriches, black bears and red foxes.
