The majority of the dry weight of a tree is derived from carbon dioxide that is absorbed from the air during photosynthesis, which is then converted into organic molecules such as carbohydrates, proteins, and fats. The minerals taken up by the roots are important for various biological functions in the tree, such as providing structural support, aiding in enzymatic reactions, and maintaining osmotic balance. However, the total amount of minerals taken up by a tree is relatively small compared to the amount of carbon dioxide it absorbs, and thus only contributes a small portion of the tree's overall dry weight.
