Variety of living Organisms
Yet diversity in life is seen in million of different types of living organisms. The five principal groups of organisms are Prokaryotes Protists Fungi Plants Animal Biodiversity The term “biodiversity” has been derived from 'bio' and 'diversity'.
Formerly it was called "natural diversity". "Diversity" means variety within a species and among species. Biodiversity is a measure of the variety of organisms present in different ecosystems Biodiversity hotspot "It is a region with a high level of established species, Plants' and animals' (flora and fauna)."
Most of the hotspofs are located in the tropics and most of them are forests. For example, Brazil's Atlantic Forest contain History of biodiversity Biodiversity found on Earth today is the result of 4 billion years of evolution The origin of llfe is not well known to science, though limited evidence suggests that until.600 million years ago, all life consisted of celled organ. Biodiversity provides food for humans.
A significant proportion of drugs are derived, directly or indirectly from biological sources. A wide range of industrial materials e.gbuilding materials, fibres, dyes, resins, gums, adhesives, rubber and oil are derived rectlyfrom biological resources. Biodiversity plays important role in making and maintaining ecosystems. It plays a part in regulating the chemistry of our atmosphere and water supply. Biodiversity is directly involved in recycling nutrients and providing fertile soil .
There is a large collection of very dissimilar forms of organisms, found on Earth. Over 1.5 million types of animals and over 0.5 million types of plants are known to biologists and these are only a small percentage of the total types estimated to live on Earth. They range in complexity from small and simple bacteria to large and complex human beings.
Some of them live in sea, some on land; some walk, others fly, and still others are stationary. Each has its own way of life i.e. getting food, avoiding unfavourable environmental conditions, finding a place to live, and reproducing its kind.
When we realize that there are so many diverse kinds of organisms, it becomes clear that no one can learn about the way of life of each. To study such a large collection, biologists classify the organisms into groups and subgroups and for this task they require some system.
Biodiversity
At least 10 million kinds of organisms have been studied and catalogued by biologists. Diversity among the Earth's organisms is more obvious than the fundamental unity of life. This diversity emerged as modifications in organisms. We see that all organisms share many biological characteristics. They are composed of one or more cells, carry out metabolism and transfer energy with ATP, and have hereditary information in DNA.Yet diversity in life is seen in million of different types of living organisms.

Dependence of Biodiversity
Diversity depends on climate, altitude, soils and the presence of other species. Biodiversity is not distributed evenly on Earth. It is rich in the tropics while there are fewer species in the polar regions. In the year 2006 large number of the Earth's species were classified as endangered or threatened species.Most of the hotspofs are located in the tropics and most of them are forests.
