Not necessarily. Consider photorespiration -- under certain conditions, some plants will use oxygen instead of carbon dioxide.

Some reactions in photosynthesis are light independent, and many plants (especially ones in hot and arid environments) will perform these reactions at night in order to conserve water.
- gus_massa 14y agoThe effect of photorespiration is that some of the oxygen is transformed back to carbon dioxide. It reduces the efficiency of the photosynthesis, so you would need more light. But it doesn't change the global amount of oxygen produced form the carbon dioxide.
