In photosynthesis, what happens to oxygen and carbon dioxide?

Explanation:
During photosynthesis, plants use light energy to turn carbon dioxide and water into sugars, releasing oxygen as a byproduct. This means the amount of carbon dioxide around the plant decreases as it is fixed into sugars, while the amount of oxygen increases as it is produced and released. So the correct outcome is that oxygen goes up and carbon dioxide goes down.
