The oxygen cycle is the biogeochemical cycle of oxygen atoms between different oxidation states in ions, oxides, and molecules through redox reactions within and between the spheres/reservoirs of the planet Earth. [1] The word oxygen in the literature typically refers to the most common oxygen allotrope, elemental/diatomic oxygen (O 2 ), as it ...
oxygen cycle, circulation of oxygen in various forms through nature. Free in the air and dissolved in water, oxygen is second only to nitrogen in abundance among uncombined elements in the atmosphere. Plants and animals use oxygen to respire and return it to the air and water as carbon dioxide (CO 2 ). CO 2 is then taken up by algae and ...
The Oxygen Cycle, which is the flow of Oxygen between air, living organisms, and the Earth's crust, plays this role. Importance of the Oxygen Cycle (Image will be uploaded soon) The Oxygen Cycle is an essential biogeochemical Cycle to maintain the concentration and level of Oxygen in the atmosphere.
1 day ago · Animals inhale oxygen and exhale carbon dioxide in the air. While plants inhale carbon dioxide and exhale oxygen during the day time and at night plants take in oxygen and give out carbon dioxide. Hence, the oxygen cycle transfers oxygen from one form to the other. In the oxygen cycle, there is the circulation of oxygen in nature.
