Document Summary
Phototroph: use light energy to assemble complex carbon-based compounds (organic) from simpler carbon-containing molecules (co2) Chemoautotroph: use energy from chemical reactions to assemble complex carbon- based compounds (organic) from simpler carbon-containing molecules. Elections are transferred from one element to another producing energy. The element that donates the electrons considered to be oxidized. The element that accepts the electron is considered to be reduced. A chemoautotroph is an organism that assembles complex organic compounds from. Co2 (complex organic compounds) iron, sulfur, and magnesium. Chemoautotrophs: embedded in the lava are numerous tubular structures left behind by ancient microbes. Tubes contain carbon that represents organic material left behind by early organisms. Photosynthetic: synthetic carbon dioxide into complex organic compounds. Stromatolites are fossilized cyanobacteria colonies, it is set up as layers that flow in a pattern, from sediments to cyanobacteria colonies. Billions of tons of oxygen due to the photosynthetic algae and photosynthesis creating a large amount of oxygen.
