FOLLOWS
• Genetic Diversity
• Species Diversity
• Ecosystem / Community
Diversity
5. • Genetic Diversity : Biodiversity includes the genetic
variations within the species, both among
geographically separated populations and among
individuals within the single population.
• Species Diversity : is defined as the number of
species and abundance of each species that live in a
particular location. The number of species that live
in a particular location is called species richness.
Abundance is defined as the number of individuals
of each species
6. Ecosystem / Community Diversity
It is the variation in the ecosystems found in a
region or the variation in ecosystems over the whole
