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)
