Autotrophs are organisms which synthesis food (glucose) as product and release oxygen as by-product in the process of photosynthesis. In the process they use carbon dioxide, water in presence of sunlight. Examples of autotrophs are green plants, algae, blue green algae. The heterotrophs use glucose and oxygen produced by autotrophs. In turn, heterotrophs release carbon dioxide during cellular respiration which is used by autotrophs. In this way autotrophs and heterotrophs benefit each other.
