Herbivores Facts

Herbivorous animals are the primary consumers that feed on plants. Cows, giraffe, kangaroos, zebras are a few herbivorous animals that feed on grass, vegetables, fruits, and plants.

Let us have a detailed look at the herbivorous animals and some of the interesting facts about them.

Facts about Herbivorous Animals

Herbivores are animals that feed on plants and fruits. The largest herbivore on earth is the African elephant. Rabbits, cows, deer, zebras are a few examples of herbivorous animals.

Types of Herbivorous Animals

Herbivorous animals are of different types. Few of them feed on a variety of plants while some feed on a specific type of plant. For eg:

  • The ones that feed only on fruits are called frugivores. Flying foxes and fruit bats are some of the frugivores.
  • The animals that feed on leaves are called folivores. For eg., panda, caterpillars, giraffe, koala, etc.
  • Herbivorous animals that feed on woods are called xylophages. For eg., termites.
  • Nectivores are herbivores that feed on nectar. For eg., butterflies.
  • The seed-eating herbivorous animals are called granivores. Eg., pigeons.

Herbivorous Animals and the Food Chain

The herbivorous animals transport photosynthetic energy in the trophic system. They are known as primary consumers. But not all the energy present in the plants will be transferred to the herbivores. Only 10% of the energy is transferred to the primary consumers. That is why the number of herbivorous animals is less than the plants on earth. Similarly, the number of carnivorous animals is less than herbivores on earth.

Protection against Predators

Herbivorous animals have several adaptations to protect themselves from enemies. Some of the adaptations include:

  • Turtles have hard shells that protect them against predators.
  • A millipede curls itself in the shape of a ball and releases a noxious substance that causes irritation in eyes and skin.
  • A few herbivores change their colour to match the surroundings to protect itself from predators.

Digestion in Herbivorous Animals

Herbivorous animals have broad and flat teeth that help to grind the cell wall of tough, fibrous plants. They do not contain the enzymes responsible for the breakdown of cellulose. They, therefore, digest the plants in either of the two ways:

  • Foregut¬†fermentation
  • Hindgut fermentation

Foregut Fermentation: In this, the bacteria process the food and breaks it down before it is digested in the animal’s stomach. Such animals have several chambers in the stomach. This separates the bacteria from the acid-secreting part of the stomach and prolongs digestion so that it gets ample time for processing. These herbivorous animals are known as ruminants. Cows, kangaroos, etc. fall under this category.

Hindgut Fermentation: This process takes place in the latter part of the gut where the food is processed and broken down after digestion. Horses, elephants and zebras use hindgut fermentation.

Frequently Asked Questions

What are herbivorous animals?

Herbivorous animals are the animals that feed on plants and fruits. Cows, buffaloes, goats, deer are some of the herbivorous animals. Herbivorous animals that feed on fruits are called frugivores, that feed on leaves are folivores while that feed on nectar are called nectivores.

What are the important characteristic features of herbivorous animals that help them to feed on plants?

The herbivorous animals have wide and flat molars that help in grinding food. The incisors in herbivores in herbivores help them to tear plants. These might be present on either the upper or the lower jaws of herbivores. They have a longer digestive tract that is beneficial for the proper digestion of cellulose present in plants.

What features of herbivores help in the digestion of food?

The herbivorous animals have several chambers in the stomach. The cellulose present in plants is difficult to digest. The long digestive system of herbivores gives ample time to the microorganisms to digest cellulose.

Why are herbivores called the primary consumers?

Primary producers form the base of the food chain and are the organisms that prepare their own food and do not feed on any organism for their food. Primary consumers are the organisms that feed on the primary producers for their nutrition. Since herbivorous animals feed on primary producers, i.e., plants for their food, they are known as primary consumers. They are the primary link between the producers and consumers and pass the energy between them.

What are the different categories of herbivores?

Herbivores can be divided into the following categories:

  • Frugivores that feed on fruits. Eg., bats
  • Folivores that feed on leaves. Eg., cows, goats
  • Grainivores that feed on seeds. Eg., pigeons
  • Nectivores that feed on nectar. Eg., Butterflies
