Answer:
Higher Photosynthesis, lower carbondioxide concentration in the atmosphere and vice versa.
Explanation:
Photosynthesis is greatly responsible for the fluctuation of carbondioxide concentration in the atmosphere because photosynthesis is the process where carbondioxide gas is used in large amount. If the vegetation occurs higher in the season, decrease will occur in the carbondioxide concentration of the atmosphere while on the other hand, if the less vegetation occur then there is higher amount of carbondioxide concentration in the atmosphere.
