2. INTRODUCTION
The term Biodiversity was coined by Walter G. Rosen in 1986.
The biosphere comprises of a complex collections of innumerable
organisms, knows as the Biodiversity, which constitute the vital
life support for survival of human races.
Biological diversity, abbreviated as biodiversity , represent the
sum of total of various life forms such as unicellular fungi,
protozoa, bacteria and multi cellular organisms such as plants,
fishes and mammals at various biological levels including gens,
habitats and ecosystems

3. CONCEPT OF BIODIVERSITY & ITS
TYPES
Biodiversity is the variety of the life on Earth.
For any kind of animals or plants-each individual is not exactly
the same as any other; nor are species or ecosystems.
Biodiversity is generally describes at three levels: genetic
diversity, species diversity and ecosystem diversity.

4. TYPES OF BIODIVERSITY
There are Three Types of Biodiversity
-Genetic Biodiversity
-Species Biodiversity
-Ecosystem Biodiversity

5. IMPORTANCE OF
BIODIVERSITY
• Biodiversity is the amount of variety of life on Earth. It is the
number of different species of plants, animals, and
microorganisms. It includes organisms from Earth’s vastly
different ecosystems, including deserts, rainforests, coral
reefs, grasslands, tundra, and polar ice caps.

6. Increase ecosystem productivity; each species in an ecosystem
has a specific niche—a role to play.
Support a larger number of plant species and, therefore, a
greater variety of crops.
Protect freshwater resources.
Promote soils formation and protection.
Provide for nutrient storage and recycling.
Aid in breaking down pollutants.
Contribute to climate stability.
Speed recovery from natural disasters.
Provide more food resources.
Provide more medicinal resources and pharmaceutical drugs.
Offer environments for recreation and tourism.
