27. When organic matter decomposes in the soil, it gives off carbon dioxide. This carbon dioxide replaces some of the oxygen in the soil pores. As a result, soil air contains less oxygen and more carbon dioxide than the air above the soil surface. Carbon dioxide is dissolved by water in the soil to form a weak acid (carbonic acid). This solution reacts with the minerals in the soil to form compounds that can be taken up and used as foods by the plants.
