This is an image of the forest behind my house in Graham, NC. We have a variety of different woody species including oaks, maples, and dogwoods. As I stood before these massive trees, I thought about how they got to that point. How did they get so tall? What fuels their growth? I have learned that the majority of their biomass actually comes from carbon dioxide taken in during photosynthesis. The carbon taken in becomes incorporated into the plant's cells and can be seen in the cell wall, DNA, and proteins. This enables the trees to continue to grow. This process illustrates the relationship between the atmosphere and biosphere. The carbon dioxide in the atmosphere allows the trees to continue to grow. As the trees continue to grow through photosynthesis, they are releasing oxygen, which changes the contents of the atmosphere.
