Photosynthesis in plants and a few bacteria is responsible for feeding nearly all life on Earth. It allows energy from the sun to be converted into a storable form, usually glucose, which plants use to grow and thrive. Photosynthesis also generates the oxygen that animals need to survive. But here we animals repay the favor. We exhale the carbon dioxide that plants need for photosynthesis. Here, take a closer look at the oxygen/carbon dioxide cycle and the process of photosynthesis.
