What are the necessary conditions for autotrophic nutrition and what are its by-products?
When the living organisms obtain food and utilizes it for the use in various biological activities like growth, maintenance and for the energy need is known as nutrition. Some nutritional elements like amino acids, fatty acids, vitamins and minerals.

There are two modes of autotrophic nutrition:-
Photoautotrophic nutrition is the preparation of organic food from inorganic material by utilizing sun’s energy (photosynthesis process) and on the other hand, chemoautotrophic nutrition or chemosynthesis is the preparation of organic food with the help of chemical reaction energy.
The necessary conditions for autotrophic nutrition are chlorophyll, sunlight, carbon dioxide, water in photoautotrophic nutrition they take carbon dioxide and water from the environment and transform these into the glucose and oxygen by the process of photosynthesis trapped by chlorophyll; and in chemoautotrophic nutrition, some bacteria develops a technique to capture energy released by the oxidation of inorganic chemical substances and make organic food. Eg. Nitrifying bacteria like Nitrosomonas and Nitrobacter.
Their by products are glucose and oxygen. And, their by products are represented in the following equation:-
