WebSep 7, 2024 · The Oxygen Cycle Photosynthesis is the driver of the oxygen cycle. In this process, plants transform CO 2 and water into sugars to use in their metabolism, help them to grow and to provide food for … WebSuch natural cycles of elements are called biogeochemical cycles. Let us look at the four elements most important for life: oxygen, nitrogen, hydrogen and carbon. Oxygen cycle The flow of oxygen Oxygen is an element that we find most important for our survival. Yet in our atmosphere there is only 20, 5% of free oxygen.

Other oxygen-containing molecules in the atmosphere include ozone (O3), carbon dioxide (CO2), water vapor (H2O), … See more The biosphere is 22% oxygen by volume, present mainly as a component of organic molecules (CxHxNxOx) and water. See more The lithosphere is 46.6% oxygen by volume, present mainly as silica minerals (SiO2) and other oxide minerals. See more The presence of atmospheric oxygen has led to the formation of ozone (O3) and the ozone layer within the stratosphere: $${\displaystyle \mathrm {O_{2}+uv~light\longrightarrow 2~O} \qquad (\lambda \lesssim 200~{\text{nm}})}$$ See more The hydrosphere is 33% oxygen by volume present mainly as a component of water molecules, with dissolved molecules including free oxygen and carbolic acids (HxCO3). See more While there are many abiotic sources and sinks for O2, the presence of the profuse concentration of free oxygen in modern Earth's atmosphere and ocean is attributed to O2 production … See more • Carbon cycle • Nitrogen cycle See more
