Answer:
Step-by-step explanation:
Seasonal fluctuations impact the amount of carbon dioxide in the atmosphere through a natural process called the carbon cycle. During the growing season, plants take up carbon dioxide from the atmosphere through the process of photosynthesis, which results in a decrease in the amount of carbon dioxide in the atmosphere. During the non-growing season, when plants are not taking up carbon dioxide, the amount of carbon dioxide in the atmosphere increases. This cycle is more pronounced in the Northern Hemisphere, where there is more land and more vegetation, resulting in a larger seasonal fluctuation in carbon dioxide levels. Human activities such as burning of fossil fuels also contribute to the increase of carbon dioxide in the atmosphere.
