Trees take in carbon dioxide through small openings on their leaves called stomata during the process of photosynthesis. They use energy from sunlight to convert the carbon dioxide and water into glucose (a type of sugar) and oxygen. The oxygen is released back into the air, while the glucose is used as energy for the tree and also stored as energy reserve.
