Autotroph
An autotroph or producer , is an organism that produces complex organic compounds (such as carbohydrates , fats , and proteins ) from simple substances present in its surroundings, generally using energy from light ( photosynthesis ) or inorganic chemical reactions ( chemosynthesis ). [1] They are the producers in a food chain , such as plants on land or algae in water (in contrast to heterotrophs as consumers of autotrophs). They do not need a living source of energy or organic carbon . Autotrophs can reduce carbon dioxide to make organic compounds for biosynthesis and also create a store of chemical energy. Most autotrophs use water as the reducing agent , but some can use other hydrogen compounds such as hydrogen sulfide . Some autotrophs, such as green plants and algae, are phototrophs , meaning that they convert electromagnetic energy from sunlight into chemical energy in the form of reduced carbon .

An autotroph [α] , ( self - feeding ) or producer , is an organism that produces complex organic compounds (such as carbohydrates , fats , and proteins ) from simple inorganic molecules using energy from light (by photosynthesis ) or inorganic chemical reactions ( chemosynthesis ). They are the producers in a food chain , such as plants on land or algae in water. They are able to make their own food and can fix carbon . Therefore, they do not use organic compounds as an energy source or a carbon source. Autotrophs can reduce carbon dioxide (add hydrogen to it) to make organic compounds. The reduction of carbon dioxide, a low-energy compound, creates a store of chemical energy. Most autotrophs use water as the reducing agent , but some can use other hydrogen compounds such as hydrogen sulfide. An autotroph converts physical energy from sun light (in case of green plants) into chemical energy in the form of reduced carbon. |
