How does photosynthesis contribute to the oxygen levels in the atmosphere?

• Photosynthesis releases carbon monoxide into the atmosphere

• Photosynthesis absorbs oxygen from the atmosphere

• Photosynthesis contributes to the oxygen levels in the atmosphere by releasing oxygen as a byproduct.

• Photosynthesis converts carbon dioxide into nitrogen
