Carbon dioxide photo-generation

As discussed in the answer to exercise 94, trees and other photo-synthetic plants absorb atmospheric carbon dioxide in the summer, which causes a decrease in atmospheric CO levels by the fall. During the winter, the plants lose their leaves and photosynthesis stops. I he fall and winter decay of the organic matter generates carbon dioxide, which increases the atmospheric CX), levels by the spring. Most of the land mass of our planet is located in the northern hemisphere. Theic-forc, that s where most of the CX)j>-coiisuming photosynthesis from ciecs and plants takes place.
