Answer 1

Biodiversity is the variety of life forms on earth that is used to define the species in one region or an ecosystem. It includes every living organism which consists of plants, bacteria, animals and human beings.

Complete answer:
Biodiversity occurs through speciation which is an evolution reappearance of new species and gets depleted by extinction. Biodiversity occurs when the evolution of a unicellular organism gets evolved into many different forms and different climatic changes lead to various types of ecosystem. The reason for biodiversity is speciation which is one of the reasons for the evolution of new species that took millions of years to generate the kind of diversity on the planet. It is important to conserve the biodiversity on our planet for maintaining the stability of earth survival. The complexity of life on earth is worked together by three different levels which include genetic diversity, ecosystem diversity and species diversity that gets explored for biodiversity.
Hunting, pollution and habitat destruction have impacted the biodiversity for about a thousand years through which the extinction takes place and there is evidence of the number of animal species that became extinct for about ten of the thousands of years ago after the arrival of the first humans that settled. the shifting boundaries of the ecosystem which gets threatened by the climatic change of the biodiversity such as the altering of the temperature and the hatching and budding.

Note:
$8\%$ of the world's biodiversity is the home for species in India. biodiversity helps us in many ways which include water cycling and soil formation. Also, it provides resistance against invasive species and the pollution that are controlled by the ecosystems.
