D Correct answer
Explanation

Photosynthesis converts atmospheric carbon dioxide (CO2) into glucose (C6H12O6) using sunlight energy, water, and chlorophyll. Transpiration is water loss, fossilization preserves organic matter, and decomposition breaks down organic material. Only photosynthesis builds glucose molecules from atmospheric carbon.
