How do trees absorb carbon dioxide?

Trees absorb carbon dioxide (CO₂) from the atmosphere during photosynthesis. Through tiny openings in their leaves called stomata, they take in CO₂ and combine it with water absorbed by their roots. Using sunlight as energy, trees convert these ingredients into glucose and oxygen. The glucose serves as food for the tree, while the oxygen is released back into the air. This process not only sustains the tree’s growth but also helps mitigate climate change by reducing the amount of CO₂ in the atmosphere.
