concentration with the highest levels measured in

May and the lowest levels measured in October.
Hypothesize how photosynthesis can affect these
changes. Explain your answer in three to five
sentences. (Remember: 1. Leaves, in the Northern
Hemisphere, appear on trees in the Spring and fall
from trees in the Autumn. 2. Leaves are where
photosynthesis occurs. 3. How does photosynthesis
effect carbon dioxide?) (4 points)

The concentration of carbon dioxide is typically higher in May compared to October because during the spring, as leaves appear on trees, photosynthesis rates increase. Photosynthesis is the process by which plants use carbon dioxide, sunlight, and water to produce oxygen and glucose. This results in a decrease in carbon dioxide levels in the atmosphere. In contrast, during autumn, as leaves fall from trees and undergo decomposition, there is a decrease in photosynthesis rates, resulting in a gradual increase in carbon dioxide levels. Therefore, photosynthesis plays a significant role in regulating carbon dioxide levels, with the highest concentrations in May and the lowest concentrations in October.
