Most organisms obtain energy from food by the process of cellular respiration. Which is the MOST LIKELY explanation for whatever Earth running out of oxygen? A. The overall reactions of photosynthesis and cellular respiration are the opposite of one another therefore the products of one are the reactants of the other, creating a cycle. OB. The energy--and thus oxygen-flows for cellular respiration and photosynthesis take place in the same direction and there to bude one another OC. Cellular respiration is a process that deposits energy and oxygen and photosynthesis withdraws energy and we are the balancing each other. OD. Oxygen readily accepts electrons, so cellular respiration uses a negligible amount of oxygen OE Cellular respiration is balanced by fermentation, an alternative process of glucose metabolism wich retums xygen​
