157. Organisms, which utilize simple inorganic compounds, are termed as        a) Phototrophs        b) Autotrophs        c) Heterotrophs        d) Necrotrophs                             An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other               chemicals.Autotrophs are a vital part of the food chains of all ecosystems.They serves as primary producers               in a food chain, such as plants on land or algae in water.Autotrophs reduces carbon dioxide (add hydrogen                to it) to make organic compounds.               Autotroph can be phototrophs or lithotrophs (chemoautotrophs). Phototrophs use light as an energy source,               while lithotrophs oxidize inorganic compounds, such as hydrogen sulfide, elemental sulfur, ammonium and               ferrous iron.They take energy from the environment in the form of sunlight or inorganic chemicals and use               it to create energy-rich molecules such as carbohydrates.
