As trees grow, what gas do they absorb and what gas do they release?

Trees play a crucial role in the process of photosynthesis, during which they absorb carbon dioxide from the atmosphere. This gas is utilized by the tree to create carbohydrates, which serve as energy sources for growth and development. As a byproduct of this process, trees release oxygen back into the environment. This exchange is fundamental not only for the survival of trees but also for maintaining the balance of gases in Earth's atmosphere, as it provides oxygen that various organisms, including humans, need for respiration.

The significance of this process makes the answer highlighting carbon dioxide absorption and oxygen release particularly important in understanding how trees contribute to ecosystem health and climate stability.
