Autotrophy — is the ability to be self sustained by producing food from inorganic compounds. Some bacteria and some archaea have this ability. Inorganic compounds are oxidized directly without sunlight to yield energy. This metabolic mode also requires energy … Wikipedia
Mixotroph — A mixotroph is a microorganism that can use a mix of different sources of energy and carbon. Possible are alternations between photo and chemotrophy, between litho and organotrophy, between auto and heterotrophy or a combination of it. Mixotrophs … Wikipedia
Microbial mat — A microbial mat is a multi layered sheet of micro organisms, mainly bacteria and archaea. Microbial mats grow at interfaces between different types of material, mostly on submerged or moist surfaces but a few survive in deserts.[1] They colonize… … Wikipedia
