The oxygen cycle is the biogeochemical cycle that describes the movement ofoxygen within its three main reservoirs: the atmosphere (air), the total content of biological matter within the biosphere (the global sum of all ecosystems), and thelithosphere (Earth's crust). It comprises about 21% of atmospheric air. The ozone layer refers to a region of Earth's stratosphere that absorbs most of the Sun's UV radiation. Oxygen is an important component of everyday life. Main process which is concerned with the liberation of oxygen is photosynthesis. It is required by organisms in the synthesis of proteins, nucleic acids, and other nitrogenous compounds.

A similar carbon cycle occurs in aquatic ecosystems between aquatic organisms and dissolved Carbon dioxide in water. step 6)This CO2 is taken by plants for the process of photosynthesis and O2 is released, and this process continues. Macromolecules like glucose, sugars, fatty acids, amino acids, etc. It is required by the organisms that respire aerobically. Carbon dioxide is released by animals and used in plants in photosynthesis. The photolysis breaks the water. During this process, plants take in carbon dioxide (CO 2) and absorb water (H 2 O) with the help of their roots. Oxygen cycle. Part of BYJU'S NCERT Geography notes for UPSC 2021.

Step 1)Animals take in oxygen through the process of respiration. Thus, they are first broken down into two-carbon compound Acetyl CoA. It is the biogeochemical cycle which explains the movement of oxygen gas within the atmosphere, the ecosystem biosphere, and the lithosphere. ADVERTISEMENTS: Nitrogen being 79 per cent of the atmosphere, the atmospheric phase is predominant in the global nitrogen cycle. We cannot survive without oxygen. But aerial nitrogen, the most abundant component of air, is rather inert chemically […] Finally, nitrification converts ammonia into nitrates.
