Different animals have different feeding habit. Some eat green plans and plant products and are called herbivores like cow and deer. Some feed on flesh of other animals and are called carnivores. Like lion. Some animals eat both plants and animals and are called omnivores, like humans, rat etc.

Introduction:
Animals obtain nutrition by consuming food, which provides them with the necessary energy and nutrients for growth, maintenance, and reproduction. There are various modes of nutrition in animals, each suited to their specific dietary requirements and feeding habits.

1. Herbivores:
Herbivores primarily consume plant material as their main source of nutrition. Their digestive systems are adapted to break down complex carbohydrates found in plants, such as cellulose. Herbivores have specialized teeth and long digestive tracts to facilitate the digestion and absorption of plant material. Examples of herbivores include cows, horses, and rabbits.

2. Carnivores:
Carnivores primarily feed on other animals. They have sharp teeth and strong jaws to capture, kill, and consume their prey. Their digestive systems are shorter compared to herbivores, allowing for quick digestion and absorption of nutrients. Examples of carnivores include lions, tigers, and wolves.

3. Omnivores:
Omnivores have a diverse diet that includes both plant and animal material. They have a combination of sharp and flat teeth to help them consume a variety of foods. Their digestive systems are adapted to handle both plant and animal matter. Examples of omnivores include humans, bears, and pigs.

4. Detritivores:
Detritivores obtain nutrition by consuming dead organic matter, such as decaying plants and animals. They play an important role in the ecosystem by recycling nutrients. Examples of detritivores include earthworms, maggots, and dung beetles.

5. Filter feeders:
Filter feeders obtain nutrition by filtering small particles from water or air. They have specialized structures, such as gills or baleen plates, to sieve out food particles. Examples of filter feeders include whales, clams, and flamingos.

6. Fluid feeders:
Fluid feeders obtain nutrition by consuming liquids, such as nectar or blood. They have specialized mouthparts, such as proboscis or needle-like mouthparts, to extract fluids. Examples of fluid feeders include butterflies, mosquitoes, and vampire bats.

Conclusion:
Animals have evolved various modes of nutrition based on their dietary requirements and feeding habits. These different modes of nutrition allow animals to adapt to their specific environments and efficiently obtain the necessary energy and nutrients for survival and reproduction.
