Some of the green plants produce their food by the process of photosynthesis. The nutrition in which organisms prepare their own food from inorganic raw materials like carbon dioxide and water is called autotrophic nutrition.
In the autotrophic mode of nutrition, organisms make their own food with simple inorganic materials like carbon dioxide and water in the presence of sunlight. Also, in this nutrition, organic food is made from inorganic materials.
Some Important facts about this is a
- Green plants have an autotrophic mode of nutrition. These organisms are called autotrophs.
- The autotrophs have green pigments called chlorophyll which help in trapping sunlight energy.
- They use sunlight to make food by the process of photosynthesis.
- The food produced by autotrophs is used by human beings and animals as well.
Autotrophic nutrition takes place through the process of photosynthesis. Carbon dioxide, water, chlorophyll pigment, and sunlight are the necessary conditions required for autotrophic nutrition.
Carbohydrates (food) and O2 are the by-products of photosynthesis.
