In the Northern Hemisphere, climate scientists observe seasonal changes in carbon dioxide 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)
Photosynthesis is the process through which plants convert carbon dioxide into oxygen and glucose, utilizing sunlight as an energy source. As spring arrives in the Northern Hemisphere, leaves appear on trees, increasing the surface area available for photosynthesis. This leads to a higher rate of carbon dioxide absorption by plants, resulting in a decrease in atmospheric CO2 concentration. Conversely, as autumn arrives, leaves fall from trees, reducing the surface area available for photosynthesis. Consequently, the rate of CO2 absorption decreases, leading to an increase in atmospheric CO2 concentration during this time. Therefore, the seasonal changes in carbon dioxide concentration can be attributed to the fluctuating rates of photosynthesis.
