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. T..

1) Some amount of phosphorus is returned to earth in the form of birds excreta - Guano deposits (excreta of marine birds) and dead fish (around 60,000 tonnes which is less than 0.5% of phosphorus discharged from rivers). 2) Death and decay of organisms and decomposition of orga..

a) It is the main constituent of energy rich compounds like ADP (Adenosine diphosphate), ATP (Adenosine triphosphate), GTP (Guanine tri phosphate) etc. b) Its a major constituent of cell membrane, nucleic acid, cellular energy transfer systems. c) Essential for metabolic reactions releasing energy...

Water is an indispensable commodity of life. Water determines the distribution, structure and function of organisms in the ecosystem. Water occurs in three phases - solid, liquid (ice/snow) and gaseous (water vapour). In liquid phase it is vital for the existence of life on this planet. In gaseous ..

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: Ca 3 (PO 4 ) 2 Fluorapatite: 3Ca 3 (PO 4 ) 2 . CaF 2 Chlorapatit..

Carbon Cycle - 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 o..

Nitrogen is an important structural component of many necessary compounds, particularly proteins. Atmosphere is the reservoir of free gaseous nitrogen and nitrogen compounds are found in bodies of organisms and in the soi..

Sulphur Cycle - Sulphur is an important component of most proteins, few vitamins and enzymes. Though sulphur occurs in gaseous form, as hydrogen sulphide (H 2 S) and sulphur dioxide (SO 2 ), the residence time of sulphur in atmosphere is very small (about 4 x 10 1 0 kg) and its ..
