1.	What are the necessary conditions for autotrophic nutrition and what are its by- products?
Answer» Autotrophic mode of nutrition involves the making of food by green plants by the process of photosynthesis. The conditions necessary for autotrophic nutrition are the presence of : Carbon dioxide, Water, Chlorophyll and Sunlight. Carbon dioxide combines with water in the presence of sunlight energy (absorbed by chlorophyll) to form food like glucose. This glucose carbohydrate is used for providing energy to the plant. A part of glucose is stored in plants as starch which can be used as a source of energy ehenever the plant need it. The major by-product of autotrophic nutrition (or photosynthesis) is oxygen gas which gose into the air.
