Quizplus · Accepted Answer

If all photosynthetic processes on Earth were to cease, carbon dioxide levels in the atmosphere would increase because there would be no organisms performing photosynthesis that take in carbon dioxide. The decrease in oxygen levels would occur because photosynthesis is the primary process that produces oxygen in the atmosphere. Therefore, without photosynthesis, there would be no significant production of oxygen, causing oxygen levels to decrease.
