A Correct answer
Explanation

Trees derive approximately 90% of their biomass from atmospheric carbon dioxide through photosynthesis, not from soil nutrients. This scientific fact surprises many people. Only about 10% comes from soil minerals and water. The massive trunk, branches, and leaves are mostly built from carbon extracted from air CO2, not from soil.
