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.
