BIODIVERSITY

 There are millions of living beings including plants, animals, birds and micro level organisms

 on the earth. There are differences and diversities among them. These diversities and 

differences in ecosystem refer to bio-diversity. This is the bio-diversity of heredity and 

species. Bio-diversity brings differences in the ecosystem where organism and gene play 

an important role. Bio-diversity of an area refers to existing organism, gene, animals, and

ecosystem per unit of land. In totality, bio-diversity refers to the existing number of living

organisms and their diversity.

Bio-diversity can be classified into three groups – species, ecosystem and genes. Man, elephant, birds, maize, wheat, pluses, potatoes and plants are included within species. The species of organism and virus are also included in them. This is the numerical counting of species. Ecosystem is a habitat for the living beings. The structure of ecosystem causes bio-diversity. Even living beings have their own heredity qualities. The people of the Himalayas have the hereditary quality to tolerate severe cold whereas those of the region can tolerate hot temperature.

Bio-diversity differs according to the geographical regions. Therefore, there are diversities in living things. Some living beings found on land, some in the water and the other in the atmosphere. Similarly, some plants are found in lithosphere whereas the others found in hydrosphere. Some plants are floating on the water while others live under it. Bio-diversity and conservation have been maintained because living beings can adjust themselves according to geographical conditions. The living beings within bio-diversity exists in association with special relationship among them. If one species in destroyed or disturbed, the whole system of living things will be affected. The negative effects on their system of living beings will disturb the whole ecosystem. For example, the forested area of any place is destroyed, the system, the vegetation, wild life and other living beings will be negatively affected. It will be difficult for them to live in their area.
