Question

What is the difference between Herbivorous carnivorous and omnivorous

Answer 1

Herbivorous animals are the animals which eat only plants.
eg :- deer
Carnivorous animals are the animals which eat other fleshy animals.
Eg :- lion
Omnivorous animals are the animals which eat both plants and fleshy bodies.
Eg :- human beings

Answer 2

Herbivores are the plant eaters and considered as primary members of the food chain. They can directly store energy, which is stored in plants. When compared to carnivores and omnivores, herbivores have characteristic teeth, which include; broad, flat, spade-shaped incisors, dull, short canines or none, and molars with flat cusps. Incisors and canines are used to pick plant pieces into the mouth while molars with wide ridged surfaces are used for grinding plant materials. Because of the low palatability of plant materials, herbivores have extensive chewing capacity. For this purpose, their jaw point is located just above the plane of teeth. Herbivores have carbohydrate digestive enzymes in saliva. However, this is unlikely to occur in carnivores and omnivores (except in human). The stomach has  either single or with multiple chambers, which improves the digestion of plant material. The length of the small intestine of herbivores is 10 to 12 times their body length; this helps to increase the absorption surface of nutrients. Moreover, their colon is long and may be sacculated, just like humans.

Carnivores are the animals that rely solely on meats of other animals. The most characteristic feature of carnivores is the presence of large canines with extremely sharp edges that are designed for stabbing and tearing the prey. In addition, their molars have jagged edges and incisors have short pointed ridges that help to grasp and shred flesh. Similar to omnivores, carnivores have no digestive enzymes in their saliva. Moreover, the length of small intestine is 3-6 times their body length. Their liver has the ability to detoxify Vitamin A unlike herbivores. The nails are modified to sharp claws. 

Omnivores are the animals that feed on both meat and vegetation. They have a great variation of dietary pattern, unlike the other two categories. Omnivores have fairly mixed dentition of carnivores and omnivores. They have short pointed incisors, long sharp curved canines and molars with sharp and / or flat blades. The length of their small intestine is 4-6 times body length. Other features like stomach capacity and type, salivary composition, colon, liver, and nails are very much similar to carnivores.
