Summary Introduction
Introduction:
Biodiversity can be described as the variety and variability found in the different forms of life on the earth. It also includes the genetic information present in the life forms and the ecosystem formed by the organisms. Biodiversity is classified into three levels, i.e., genetic diversity, species diversity, and ecosystem diversity.
