SOQ # 8 1. Define autotrophs and heterotrophs.  Which are most prevalent on the Earth? a. Autotrophs-"self-feeders", use chemical energy b. Heterotrophs- "fed by others", live on the energy autotrophs produce c. Heterotrophs make up 95% of the organisms on Earth-all animals and fungi, and  most protists and prokaryotes-are heterotrophs 2. Distinguish between aerobic respiration, anaerobic respiration and fermentation. a. Aerobic respiration-during cellular respiration depleted electrons are transferred  to a final electron acceptor, in aerobic respiration it is oxygen b. Anaerobic respiration-the final electron acceptor is an inorganic molecule, but is  not oxygen c. Fermentation- the final electron acceptor is an organic molecule 3. How do cells use ATP to drive endergonic reactions?  How much energy is released from  one mole of ATP ---> ADP + P? a.
