What are the necessary conditions for autotrophic nutrition, and what are its byproducts?

Solution:

• The energy and carbon requirements of the autotrophic organism are obtained by the process of photosynthesis.
• It is defined as the process by which autotrophs take in substances from the outside surroundings and convert them into stored forms of energy.
• This substance is taken in the form of carbon dioxide and water, which are converted into carbohydrates in the presence of sunlight and chlorophyll.
• The main purpose of carbohydrates is to provide energy to the plant. The carbohydrates are not utilised immediately, but they are stored in the form of starch, which serves as an internal energy reserve.
• The stored energy can be used as and when required by the plant.
