The seasonal changes in atmospheric carbon dioxide concentration can be attributed to the timing of photosynthesis in the Northern Hemisphere. In the spring, as trees and plants produce new leaves, photosynthesis increases, utilizing carbon dioxide as a key input process. This increased photosynthetic activity leads to a significant uptake of carbon dioxide from the atmosphere, resulting in the highest levels measured in May. Conversely, as autumn approaches, leaves fall from trees and photosynthesis decreases sharply, leading to a reduced uptake of carbon dioxide. This shift results in higher atmospheric carbon dioxide levels by October, as the reduction in photosynthesis allows for increased carbon dioxide accumulation.
Climate scientists have observed seasonal changes in atmospheric carbon dioxide concentration. In the Northern Hemisphere, they have measured the highest levels of carbon dioxide in the month of May. They have also measured the lowest levels of atmospheric carbon dioxide in the month of October. Hypothesize how photosynthesis can affect these changes. Consider the process of photosynthesis and its inputs and outputs. Explain your answer in three to five sentences.
Things to keep in mind as you develop your hypothesis:
In the Northern Hemisphere, leaves appear on trees in the spring and fall from trees in the autumn.
Leaves are where photosynthesis occurs.

can you edit it to two sentence's?
The seasonal changes in atmospheric carbon dioxide concentration in the Northern Hemisphere are influenced by photosynthesis, which peaks in spring when new leaves emerge and absorb carbon dioxide. As photosynthetic activity declines in autumn with leaf fall, less carbon dioxide is absorbed, leading to higher atmospheric levels by October.
