Answer / Solution

In autotrophic nutrition, organisms such as green plants prepare their own food by the process of photosynthesis

Photosynthesis is a process in which carbon dioxide and water, in the presence of sunlight and chlorophyll, are converted into carbohydrates. We can understand this prcess by this chemical equation 

The three basic conditions are necessary for autotrophic nutrition, these are

  1. The availability of carbon dioxide and water
  2. Presence of chlorophyll pigments in the leaves
  3. In the presence of sunlight, the main product of photosynthesis is carbohydrate or glucose and the by-product of photosynthesis or autotrophic nutrition is oxygen.

Answer / Solution

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.
