Introduction
What is Biodiversity ?
The word 'biodiversity' is a contraction (short form) of biological diversity. Diversity is a concept which refers to the range of variation or differences among some set of entities; biological diversity thus refers to variety within the living world (here a habitat).
The term 'biodiversity' is indeed commonly used to describe the number, variety and variability of living organisms.
From the above explanation it is clear that biodiversity is the variety or different living organisms present in a particular habitat.
Meaning of the word Biodiversity.
As read from d above explanations Biodiversity, Biodiversity can be broken down and represented like this
Biodiversity=Biological+ Diversity
Biological=Consisting of all living beings
Diversity=Variety
Types of Biodiversity
There are three major kinds of Biodiversity they are:-
1. Diversity of species- Number of different species that are present in the universe(>1.7Million)
2. Genetic Diversity-Here the inside a species there are different configurations.
3. Ecosystem Diversity- Variety of habitats around the world eg.Deserts ,Tundra’s,Marine ecosystem
DISTRIBUTION OF BIODIVERSITY
Flora and fauna diversity depends on-
Climate
Altitude-Refers to Hilly areas
Soils
Presence of other species Most of the biodiversity concentrated in Tropical region.
BIODIVERSITY AND BALANCE OF NATURE
Tropic Level: Elimination of species from tropic level can cause destruction of ecosystem as well as biodiversity.
Complex Ecosystem: In a complicated ecosystem having several tropic levels, loss of one or more spices do not cause any serious problem because the alternative available.
Keystone Species: Loss or addition of species causes detectable changes in ecosystem rates i.e. species make unique contribution to ecosystem functioning.
Niche Complementary: Difference among species in their requirements for
