Scientists tell us that if you take six molecules of carbon dioxide and combine it with twelve molecules of water, then add light, the result will be one molecule of glucose sugar, six molecules of oxygen, and six molecules of water. This process, known as photosynthesis, makes the world as we know it possible. Carbon dioxide, which is exhaled by all mammals, is converted into oxygen which allows us to breathe. Plants, which use this photosynthesis process, make our world possible. But, photosynthesis without light is not possible. The chemical reaction will not occur without light.
