Oxygen cycle: Learn about the Oxygen

Learn about the Oxygen Cycle – its definition, key examples like photosynthesis and respiration, uses in biology, how oxygen is produced, and interesting facts about this important element. Similar to other biogeochemical cycles, such as the water cycle and the carbon cycle, the oxygen cycle describes the movement and transformation of oxygen through different components of the Earth's atmosphere, lithosphere (Earth's solid outer layer), and biosphere (all living organisms). Learn about the oxygen cycle, a biogeochemical cycle that involves the transformation of oxygen in various forms in the atmosphere, biosphere, hydrosphere, and lithosphere. Find out the sources, properties, and importance of the oxygen cycle for life on Earth. The oxygen cycle is a fundamental biogeochemical cycle that describes the movement of oxygen within and between the Earth's atmosphere, biosphere, lithosphere, and hydrosphere.
