Answer 1

Hint:-The national government nominated area which involves the ecosystem of both Terrestrial and coastal for promoting the conservation of biological diversity and research of protected species is known as biosphere reserves. There are 18 biosphere reserves established by the government of India.

Complete answer:
Biosphere reserves involve the protection of the whole ecosystem for sustainable use. In 1968, the first Biosphere reserve maintenance was started. There are above 600 Biosphere reserves that are established worldwide. The main purpose of establishing the biosphere reserves is to protect the species.
Biosphere reserves comprise 3 zones. These are Core, Buffer zone, and Manipulation zone. The core area of the biosphere reserve is the highly protected exclusively area where human involvement is strictly prohibited. The information which is collected from the core area of the biosphere reserve is used to maintain the environmental qualities. It is the innermost area of the biosphere reserve. The area which occupies next to the core zone in the biosphere reserve is called the buffer zone. The buffer zone involves human activities like agriculture, natural vegetation, fisheries, etc. This area of the biosphere reserve is mainly used for research and education. The third zone of the biosphere reserve is called the manipulation zone. This is the outer region of the biosphere reserve. With the help of management bodies of the biosphere reserve, the manipulation zone is used for cropping and forestry for the improvement of the damaged region.

So the correct option is D. A protected area for the whole ecosystem.

Note:- The establishment of biosphere reserves includes several benefits. These are conservation of organisms with its habitat, maintaining the genetic diversity, restoration of the ecosystem by protecting the living beings and it’s the environment, development of economic as well as social and cultural aspects.
