Can one process go on continually without the other? be sure to support your answer with what you have learned about each process. (photosynthesis and aerobic respiration)

I don't think one process can go on continuously without the other. Because during the photosynthesis carbon dioxide is necessary along with sunlight, water to make glucose and oxygen. Without oxygen we won't survive if we don't survive then there will be no carbon dioxide. Aerobic respiration is when you take in oxygen made by plants in the process of photosynthesis as the product of aerobic respiration we breath out carbon dioxide which plants use to make glucose and oxygen.
