Navah writes out the chemical equation for photosynthesis. She includes two reacting molecules to the left of the arrow and two resulting molecules to the right.What must be added to the chemical equation to more accurately represent photosynthesis?

Photosynthesis uses light energy to convert carbon dioxide and water into glucose and oxygen. The light supplies energy for the reaction, so it is commonly written above the arrow rather than as a reacting molecule. Therefore, add light energy above the arrow.
