Nutrition and its types ncert

Nutrition is the process of taking in food and converting it into energy and other vital nutrients required for life.

Types of Nutrition

There are two types of nutrition among living organisms, namely:

  • Autotrophic Nutrition
  • Heterotrophic Nutrition

Autotrophic Nutrition

“Autotrophic nutrition is a process where an organism prepares its own food from a simple inorganic material like water, mineral salts and carbon dioxide in the presence of sunlight.” The term “autotrophic” is formed by the combination of two terms, “auto” meaning self, and “trophic” meaning nutrition.

Examples of autotrophic nutrition include Auto-Green Plants, Algae, Phytoplankton, Seaweed, Wheat, Grass, Maize plant, bacteria, blue-green algae, and Cyanobacteria.

Heterotrophic Nutrition

Heterotrophic nutrition is the mode of nutrition in which an organism depends on other living organisms for food.
