Answer:
The lowest carbon dioxide concentration occurs close to the forest because they are heavily populated with plants and photosynthesis, the process by which plants use the sun's energy to convert water and carbon dioxide into sugar. Based on the chemical equation, 6c02 + 6h20 > C6h106 + 602, plants take in carbon dioxide when this process occurs. Since photosynthesis is constantly occurring, plants are constantly taking carbon dioxide in. So, areas with a heavy concentration of plants have a low concentration of carbon dioxide.
