Autotrophic Nutrition Definition Class 10

Autotrophic Nutrition

Autotrophic nutrition is a mode of nutrition in which organisms are able to produce their own food from inorganic substances. Autotrophs, also known as producers, are able to carry out photosynthesis or chemosynthesis to produce organic molecules that serve as their source of energy and nutrients. In photosynthesis, autotrophs use light energy to convert carbon dioxide and water into glucose and oxygen. In chemosynthesis, autotrophs use energy from chemical reactions to convert inorganic molecules into organic molecules. Autotrophic nutrition is an important process in the food chain, as it forms the base of the ecosystem by providing energy and nutrients for heterotrophs (consumers) that are unable to produce their own food. Examples of autotrophs include green plants, algae, and some bacteria.
