Animals require constant energy to stay alive, active and to carry out different life processes. As animals cannot prepare their own food, they depend on plants and other animals for their food and energy. Depending upon the mode of nutrition, plants are classified as herbivores and carnivores.

Let us learn more about the  difference between herbivores and carnivores and their characteristics.

Herbivores are animals that depend on plants and plant products for their food. They have certain specific features that help them feed on plants. They have broad and flat teeth that help them to grind the plants easily. They have the capacity of detoxifying vitamin A in the liver. They possess carbohydrate  digestive enzymes  in saliva. The intestine is very long. Cows, buffaloes, goats, deer are some of the herbivores.

Carnivores are animals that depend on other animals for their food. They have sharp teeth that help them to tear through the skin. Their sharp claws help them catch their prey. However, unlike herbivores, they cannot detoxify vitamin A in the liver and do not contain carbohydrate digestive enzymes in saliva. The length of the intestine is also small. Tiger, lion, wolf, etc are some of the carnivores.
