Question

Quizplus · Accepted Answer

Photosynthesis is the only process that decreases the amount of carbon dioxide in the atmosphere by using it to create organic molecules (such as glucose) and releasing oxygen in the process. The other processes listed either release carbon dioxide (respiration, combustion) or do not directly affect its levels (decomposition, aerobic respiration).
