Question

what are the the oxidation & reduction part in the :
1) carbon cycle 2) phosphorus cycle 3)Nitrogen cycle 4) sulphur cycle ​

Answer 1

Answer:

carbon cycle

Explanation:

its a part of oxidation and reduction

Answer 2

answer:

1. The global redox carbon cycle consists of the oxidized and the reduced branches. The oxidized branch is presented by carbon dioxide, bicarbonate and carbonate species, composing common chemical exchange system in the atmosphere and hydrosphere. ... The redox carbon cycle has appeared simultaneously with photosynthesis.
2. Phosphorus in the oceans cycles between +5 and +3 oxidation states. Most of the oceans' phosphorus is present as oxidized bioavailable phosphate (+5) compounds. On a global scale, this phosphorus redox cycle adds as much reduced phosphorus to the oceans as all pre-anthropogenic land runoff. ...
3. Nitration (Oxidation of nitrite to nitrate) Step 1. Nitrite oxidized to nitrate. Step 2. Protons, electrons and oxygen are converted into water.
4. Steps of the sulfur cycle are: Mineralization of organic sulfur into inorganic forms, such as hydrogen sulfide (H2S), elemental sulfur, as well as sulfide minerals. Oxidation of hydrogen sulfide, sulfide, and elemental sulfur (S) to sulfate (SO42−). Reduction of sulfate to sulfide.
