Answers
Answer:
(A)
Explanation:
A biosphere reserve is a unique protected area which is different from a national park because:-
1) It is meant for the conservation of genetic resources, species and the ecosystem.
2) It helps in scientific research.
3) It also helps to promote sustainable development.
National parks are primarily for the conservation of species and secondarily for scientific research.
Biosphere reserve has three zones namely core area (includes protected areas), a buffer zone (surrounds and protects the core area) and transition zone (the large outer area where people live and work and use the natural resources of that area).
So, the correct answer is 'The transition zone is legally protected as undisturbed ecosystem'.
