Through photosynthesis, plants use sunlight & produce sugar from carbon dioxide & water. Sugar is produced to grow. In this process, oxygen gas is produced as a waste product which is taken by human beings for breathing. At that time, a man gives carbon dioxide & this carbon dioxide is taken by plants.
