Nutrition in Animals for Class 7: Essential Dietary Insights

Proper nutrition is essential for the growth, development, and overall well-being of animals. Just like humans, animals require a balanced diet consisting of various nutrients to stay healthy and active. In this article, we will explore the different aspects of nutrition in animals, including the types of nutrients they need, the process of digestion, and the various modes of nutrition. Lets learn more about it.


Types of Nutrients Required by Animals

Animals require different types of nutrients to support their bodily functions. These nutrients can be broadly classified into six categories:

  1. Carbohydrates: These are the primary source of energy for animals. They are found in foods such as grains, fruits, and vegetables.
  2. Proteins: Proteins are essential for the growth and repair of tissues in the body. Foods like meat, eggs, and dairy products are rich sources of proteins.
  3. Fats: Fats serve as a concentrated source of energy and also help in the absorption of fat-soluble vitamins. They are found in foods like nuts, seeds, and oils.
  4. Vitamins: Vitamins are required in small quantities but play a crucial role in various physiological processes. Animals need vitamins such as A, B, C, D, E, and K for different functions.
  5. Minerals: Minerals like calcium, phosphorus, iron, and potassium are essential for maintaining strong bones, regulating body fluids, and carrying out other important functions.
  6. Water: Water is vital for the transportation of nutrients, regulation of body temperature, and the elimination of waste products from the body.

The Process of Digestion in Animals

After intake of food, animals undergo the process of digestion where the complex food substances are broken down into simpler forms that can be absorbed and utilized by the body. The process of digestion in animals involves mechanical and chemical processes and occurs in different parts of the digestive system.

The digestive system of animals comprises organs such as the mouth, esophagus, stomach, small intestine, and large intestine. Each organ plays a specific role in the digestion and absorption of nutrients. For example, the mouth helps in the mechanical breakdown of food through chewing and mixing with saliva, while the stomach carries out the chemical breakdown of food using digestive enzymes and acids.

Modes of Nutrition in Animals

Animals exhibit various modes of nutrition based on their dietary habits and type of food they consume. The three main modes of nutrition in animals are:

Mode of Nutrition Description Examples
Herbivorous Animals that feed on plants and plant products. Cows, goats, and rabbits.
Carnivorous Animals that primarily consume the flesh of other animals. Lions, tigers, and eagles.
Omnivorous Animals that have a diet consisting of both plant and animal matter. Humans, bears, and pigs.
