उत्तर
Biodiversity itself is a combination of two words, Bio (life) and diversity (variety).
In simple words, biodiversity is the number and variety of organisms found within a specified geographic region. It is a result of hundreds of millions of years of evolutionary history. Biodiversity can be discussed at three levels:
- Genetic diversity;
- Species diversity;
- Ecosystem diversity.
- Genetic diversity: Genetic diversity refers to the variation of genes within species.
- Species diversity: Species diversity refers to the variety of species. It relates to the number of species in a defined area. The diversity of species can be measured through its richness, abundance and types.
- Ecosystem diversity: The broad differences between ecosystem types and the diversity of habitats and ecological processes occurring within each ecosystem type constitute the ecosystem diversity.
