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

Dear Student

For autotrophic nutrition to take place the conditions necessary are light, carbon dioxide and water should reach a cell which contains chlorophyll in it. Water first splits to release oxygen and hydrogen. This process is photolysis of water. Hydrogen then combines with carbon dioxide to form glucose.
The byproduct of the autotrophic nutrition is oxygen which is released through stomata.

​Thanks
