Question

What are the necessary conditions for autotrophic nutrition and what are its by product

Answer 1

Dear student,

Conditions required to carryout autotrophic mode of nutrition are:

1) Presence of chlorophyll: Chlorophyll is necessary to absorb sunlight and convert it to energy containing chemical molecules.

2) Sunlight: sunlight provides the source of energy for photosynthesis.

3) Carbon dioxide: It provides carbon for the synthesis of sugars.

4) Water: It acts as the source of electrons and oxygen during the process of photosynthesis.

Carbohydrates (food) and O₂ are the by-products of photosynthesis.

6CO₂ + 6H₂O $\underset{chlorophyll}{\overset{sunlight}{\to }}$ C₆H₁₂O₆ + 6O₂
