The video explains the oxygen cycle, highlighting how oxygen is absorbed by the lungs, used in cells, and transformed into water. It discusses the role of water in photosynthesis, where plants convert CO2 into carbohydrates. The cycle continues as humans consume these carbohydrates, breaking them down in cells to release CO2, which is then exhaled and taken up by plants again.
