How do trees produce oxygen?

Trees produce oxygen through the process of photosynthesis. During this process, trees absorb carbon dioxide from the air and water from the soil through their roots. Using sunlight, chlorophyll in the leaves converts the carbon dioxide and water into glucose (a form of sugar) and oxygen. The oxygen is then released into the atmosphere, while the glucose is used as energy for the tree’s growth. This process helps maintain the balance of gases in the atmosphere and supports life on Earth.
