It's a crazy question
carbon dioxide :p
molecules of CO2
2 molecules are produced
Carbon Dioxide is Used during Photosynthesis, and Oxygen is released after the process.
Carbon dioxide
carbon dioxide
Photosynthesis uses carbon dioxide as a raw material where carbon dioxide is fixed into organic molecules. This process lowers the level of carbon dioxide in the atmosphere. The seasonal fluctuation of carbon dioxide levels during a year may be caused by increased photosynthesis during spring and summer.
Carbon dioxide is released during the light reaction.

Carbon dioxide is released during the light reaction.
Aerobic respiration Glucose + Oxygen = Water + Carbon dioxide
