an organism that can use CO2or CO3- (i.e., inorganic C) as a C source, and obtain energy from the sun (photo) - or from the oxidation of inorganic elements or compounds such as iron, sulfur, hydrogen, ammonium, and nitrites (chemo)? correct answer: Autotroph such as plants, algae, cyanobacteria, etc. an organism that can only get carbon and energy from organic compounds? correct answer: Heterotroph such as bacteria, fungi, protozoa, etc. an organism that grows only in the presence of mol...

UTA MICROBIOLOGY LAB 5-8 PRACTICAL 2 LATEST UPDATE GRADED A+ aerobic respiration Respiration that requires oxygen anaerobic respiration Respiration that does not require oxygen. Alternatives to O2 are utilized as the final electron acceptor in the electron transport chain. These alternatives include nitrate (NO3 − ), sulfate (SO4 2−), sulfur (S), and carbonate (CO3 2−). fermentation Organic molecules like pyruvate and pyruvate derivatives act as the final electron accep...
