Explain the three important levels of biodiversity.

Explanation

The earth hosts an immense variety of living organisms.
According to a survey the number of species that are known and described are between 1.7-1.8 million.
The number refers to the biodiversity on the earth.
The term Biodiversity or Biological diversity means the number and types of organisms present on the earth, form of life in the living world.
The living world includes all the living organisms such as micro organisms, plants, animals and humans.
Biodiversity is not limited to the existing life forms.
If we explore new areas even old ones, new organisms are continously being added.
This huge available variety cannot be studied and identified without having a proper system of classification and Nomenclature.
