Question

What does the Iron Cycle involve?

Answer 1

Iron cycle:

1. It is a cycle of iron through the atmosphere, hydrosphere, biosphere, and lithosphere where Fe is abundant in the earth's crust, it is less common in oxygenated surface waters.
2. The iron cycle is the conversion of ferrous iron to ferric iron and then back again.
3. Ferric iron reduction forms a part of the respiratory pathway in some microorganisms.
4. Some bacteria are capable of producing magnetite.
5. Fe²⁺ is abiotically oxidized to Fe³⁺ in the presence of oxygen, and the reduction of Fe³⁺ to Fe²⁺ by iron-sulfide minerals in the abiotic process of the iron cycle
6. The biological cycling of Fe²⁺ is done by iron-oxidizing and reducing microbes.
