Nutrients are the components found in our food such as carbohydrates, vitamins, minerals, fats, etc. These components are necessary for living organisms to survive. Plants produce their own food while animals and human beings do not produce their own food. We indirectly or directly depend on plants and animals for our food needs.

Modes Of Nutrition

The process of obtaining food and utilizing it to grow, stay healthy and repair any damaged body part is known as nutrition. Plants produce their food by taking raw materials from their surroundings, such as minerals, carbon dioxide, water and sunlight. There are two modes of nutrition:

Autotrophic – Plants exhibit autotrophic nutrition and are called primary producers. Plants synthesis their food by using light, carbon dioxide and water.

Heterotrophic – Both animals and human beings are called heterotrophs, as they depend on plants for their food.
