Recall that in the northern hemisphere, atmospheric CO₂ levels are highest in early spring and lowest in early fall. What accounts for this seasonal fluctuation in atmospheric CO₂ levels?

Question

Quizplus · Accepted Answer

In the northern hemisphere, spring brings increased sunlight and warmth, which leads to higher rates of photosynthesis by plants. Photosynthesis is the primary process that removes atmospheric CO₂, resulting in decreased atmospheric CO₂ levels. Therefore, the highest atmospheric CO₂ concentrations occur in early spring, when photosynthetic activity is at its lowest.
