Traces of metal is necessary for the human and animal system to function efficiently. Some of the important metals required are iron, copper, zinc, sodium and potassium. Iron metal is a constituent of haemoglobin in blood which carries oxygen to various parts of the body in huma..

Phosphorus is an essential nutrient to biological systems. Its requirement is mainly seen in nucleic acids, cell membrane, bones and tee..

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..

Organisation refers to a kind of structure or system or situation where the smaller components become arranged into larger ones in a hierarchical order of complexity, to co-ordinate with one another in performing common functions or achieving common goals. In the living..

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: Ca 3 (PO 4 ) 2 Flu..

The present system of classification, recognises the living organisms under five kingdom..

Summary - Biologists estimate that there are about 30 million species of living organisms inhabiting this biosphere and only a million and half of it have been discovered and described so far. The species of plants and animals identified so far exhibit a great deal of variation in their f..

Summary - In the modern system of classification, living organisms are grouped under five kingdoms, as proposed by Whittaker (1966). The Kingdom Monera includes bacteria and blue green algae, both of which possess prokaryotic cells. Bacteria are unicellular prokaryotes that have..

Functions - The nervous system carries out the following functions i) It perceives the changes around us through our senses. ii) It controls and coordinates all the activities of the muscles in response to the changes outside. iii) It also maintains the internal enviro..
