The statement that does NOT model photosynthesis is:
6H2O + 6O2 + light → C6H12O6 + 6CO2
This equation is incorrect because it suggests that water and oxygen are reactants, which is not the case in photosynthesis. Instead, the correct inputs for photosynthesis are carbon dioxide and water, yielding glucose and oxygen. The correct equation should maintain the relationship of reactants and products as in the other options provided.
