How can seasonal fluctuation in atmospheric CO₂ be linked with vegetation?
Answer and explanation
Correct answer: Photosynthesis during the active growing season can reduce atmospheric CO₂
The governing concept is the carbon cycle. During a vigorous growing season, green plants absorb atmospheric CO₂ as a raw material for photosynthesis and release oxygen. Therefore, increased vegetation activity can temporarily lower CO₂, while seasonal leaf fall, reduced growth and respiration can raise it again. Option D is correct; the other options incorrectly deny this biological exchange or assign CO₂ an impossible source.
