Where does the oxygen that we breathe come from? (Multiple Choice) - Water
- Carbon Dioxide
- Light
- Sugar

Hydrolysis of water is the process by which water divide to form oxygen, hydrogen ion. Option A is correct. The oxygen we breath is come from the hydrolysis of water during photosynthesis.

Photosynthesis:

It is the process by which plants produce sugar using Carbon dioxide and water in the presence of sunlight.

This completes in two phases

Light Dependent Dark phase

Light Dependent Phase:

Water hydrolyses to produce oxygen, proton, and electrons.Two molecule of water hydrolyses to form one molecule of Oxygen.Oxygen is then released by plant via stomata.Carbon dioxide used in dark phase to produse carbonic acids.

Therefore the oxygen we breath is come from the hydrolysis of water during photosynthesis.

Explanation:

Scientists agree that there's oxygen from ocean plants in every breath we take. Most of this oxygen comes from tiny ocean plants – called phytoplankton – that live near the water's surface and drift with the currents. Like all plants, they photosynthesize – that is, they use sunlight and carbon dioxide to make food.

I would rate it a 6 or a 7 and A cause that is awkward.
