Detailed explanation-1: -Herbivores are organisms that feed exclusively on plants. Cow, deer and elephant are examples of herbivores. Carnivores are organisms that depend on other animals for their food. Omnivores are organisms that depend on both plants and animals for their food.

Detailed explanation-2: -Animals that eat only plants are called herbivores. Deer, grasshoppers, and rabbits are all herbivores. There are lots of different plants and lots of different herbivores. Some herbivores eat only part of a plant.

Detailed explanation-3: -Animals that eat only plants are called herbivores (or primary consumers). Animals that eat other animals are called carnivores. Carnivores that eat herbivores are called secondary consumers, and carnivores that eat other carnivores are called tertiary consumers.

Detailed explanation-4: -Herbivores form an important link in the food chain because they consume plants to digest the carbohydrates photosynthetically produced by a plant. Carnivores in turn consume herbivores for the same reason, while omnivores can obtain their nutrients from either plants or animals.
