<em>Obligate anaerobes</em> are microorganisms killed by normal atmospheric concentrations of oxygen. A <em>facultative anaerobe</em> prefers to produce energy in the presence of oxygen but can survive without it. <span>A <em>photoautotroph </em>is an organism that converts light energy into chemical energy. </span><span>Prokaryotes may perform </span>aerobic<span>(oxygen-requiring) or </span>anaerobic<span> (non-oxygen-based) metabolism and some can switch between these modes. Since we're talking about an environment without oxygen and dies when exposed to oxygen, the preferable answer is A.</span>
the answer is B. OBLIGATE anaerobe. it is the only one that is poisoned by oxygen. if you want to see for yourself just type into google (obligate anaerobe) Took the test and got a 100% :)
Rice, bread, pasta, and snacks made from white flour are missing their healthy fiber, vitamins, and minerals. Refined grains quickly convert to sugar, which your body stores as fat. A diet high in refined grains can cause belly fat, which studies link to heart disease and type 2 diabetes
The chemolithophs are the prokaryotes which uses inorganic matter in order to make organic materials for the other processes.
These organism get energy by the oxidation of the inorganic compounds. The organism such as human beings breaks down the organic compounds in order to get energy and nutritional building block.
The macro molecule used by the organism is carbon dioxide.
