How can seasonal variability of atmospheric CO2 be linked with vegetation?
Answer and explanation
Correct answer: Photosynthesis during the growing season can reduce CO2
The governing concept is the seasonal carbon cycle. During a vigorous growing season, plants absorb atmospheric CO2 for photosynthesis and use carbon to build biomass, so atmospheric concentration may decline. In colder or drier seasons, photosynthesis weakens while respiration and decomposition continue, often causing CO2 to rise. Thus option A correctly links vegetation with seasonal CO2 variation; the other choices deny this cycle or confuse CO2 with nitrogen and volcanic sources.
