Classification of biodiversity
Biodiversity exists on several levels:

6.
Genetic diversity
Includes the differences
in DNA composition
among individuals
within a given species
Adaptation to particular environmental conditions
may weed out genetic variants that are not
successful.
But populations benefit from some genetic
diversity, so as to avoid inbreeding or disease
epidemics. 6Northern India Engineering

7.
Species diversity
The number or variety of
species in a particular region
Species richness = number of species
Evenness, or relative abundance = extent to
which numbers of different species are
equal

Ecosystem diversity
Includes diversity
above the species
level
Biologists have viewed diversity above the
species level in various ways. Some alternative
ways to categorize it include:
Community diversity
Habitat diversity
Landscape diversity

Why is biodiversity important ?
It maintains a healthy biosphere and
provides both direct and indirect
benefits to humans such as food,
medicines, clothing and shelter!

Benefits of biodiversity
Conserving biodiversity preserves
ecosystem services, and directly provides
things of pragmatic value to us.
• Food, fuel, and fiber
• Shelter and building materials
• Air and water purification
• Waste decomposition
• Climate stabilization and moderation
• Nutrient cycling
• Soil fertility
• Pollination
• Pest control
• Genetic resources 10
