The main difference between Herbivores, Carnivores & Omnivores is there diet. Herbivores only eat grasses, plants, flowers and sometimes wood while carnivores are just the opposite, they only eat meats. But omnivores are right in the middle of each of these, they eat all the things that herbivores eat and all the things that carnivores eat.
Another difference between all of these is their jaws and teeth. For instance, carnivores have to have wide mouths and strong jaw muscles in order for them to eat some of the thing they eat. Herbivores on the other hand are just the opposite, they have a small mouth and a strong tongue so it’s easier for them to move food around in their mouth and grind it on the flat molar teeth in the back of their mouth. Omnivores have flat molar teeth that they use for grinding like herbivores’ and they have sharp teeth to tear off meat like carnivores.
Swallowing is another thing that set these three apart. Omnivores and herbivores have enzymes in there spit to help break down the plant and other food that they eat while carnivores do not have enzymes to help them break down food, they just swallow the chunks whole because if they had enzymes that help them break down protein, it would damage the inside of their mouth. Omnivores and herbivores chew their food so they can tear though the strong outer wall of the plant.
Carnivores have very large stomachs, so large that it can hold between 60 and 70 percent of their whole digestive tract. But herbivores have very small stomachs and they process smaller piles of food. Carnivores process food more quickly because their stomach acid level is 1 to 2 pH all the time. Herbivore process food because they have less acidic stomach juices. Some herbivores that eat things that are more difficult to digest have stomach chambers. Animal that have these are called ruminants.
Carnivores and omnivores can be very similar when it comes to inside organs. They both have simple digestive tracts and liver. Their liver can detoxify vitamin A, and herbivores cant.
