Biogeochemical Cycles - Earth is the source of matter for all living organisms, as they require several (about 40) elements for their growth and life processes. Some elements and their compounds have an important role in the living protoplasm and are required in large amounts. These nutri..

Elemental phosphorus is obtained by heating phosphate rock with coke and silica in an electric furnace at about 1770 K. The phosphorus so formed is white phosphorus..

Biogeochemical cycles are basically of two types: a) Gaseous cycles like carbon (as carbon dioxide), oxygen, nitrogen, etc. b) Sedimentary cycles like sulphur, phosphorus, etc. In gaseous cycles, the elements have a main reservoir in the gaseous pha..

Occurrence and Uses of Phosphorus - Phosphorus is widely distributed in nature. It does not occur in free state since it can be very easily oxidised. It is usually present in rocks in the combined state as phosphates. The main phosphate rocks are: Phosphorite..

Oxygen is another essential element for living organisms. It is present in large quantities (20.95% v/v) in the atmosphere and is also seen in bound state in water and as oxides and carbonates in rocks..

Carbon is found as graphite and diamond in nature. It also occurs as carbon dioxide in the atmosphere. Because of the position of its electrons, an atom of carbon can form covalent bonds with hydrogen, oxygen, nitrogen, phosphorus and other carbon atoms. Because of this versatility, the c..

Oxygen Cycle - Oxygen is another essential element for living organisms. It is present in large quantities (20.95% v/v) in the atmosphere and is also seen in bound state in water and as oxides and carbonates in rocks. Dissolved oxygen in water is the source of oxygen for aquatic..
