National parks are the land areas set aside by a national government in order to preserve the natural environment. These are the protected areas where, land, plants as well as animals are kept for conservation. They help in the prevention of landslides and floods in the nearby areas.
In a national park, protection is provided to the entire ecosystem.
The national park is a reserved area used for conservation purposes, which is maintained by the government. Cultivation, grazing, forestry, and habitat manipulation are not allowed. They provide plants and animals with a safe place to survive and reproduce. Also, they act as a home to several endemic species and protect places for natural beauty.
Therefore, Protection is provided to the entire ecosystem.
The term ‘biodiversity’ is derived from the two words- ‘bios' which means life and ‘diversity’ i.e, differentiation or variation. Edward Wilson, the sociobiologist was the first to popularise the term ‘biodiversity’ in the year 1992. The term implies the occurrence of various plants and animals along with their variants such as biotypes, ecotypes and genes on earth. In our biosphere, the immense diversity or heterogeneity remains not only at the species level but also, at every level of biological organization that ranges from macromolecules in the cells to biomes.
Biodiversity and Conservation is a topic covered under the fifteenth chapter and Unit 5 of NCERT class 12 biology.
