Chlorophyll-containing structures capture light energy, supporting reactions that form organic molecules from carbon dioxide. The familiar overall equation summarises many linked processes rather than one instantaneous collision. Changing a required input in this diagram changes whether the simplified route can operate. It does not calculate a real crop yield or claim that more light always gives unlimited growth.
