Differentiate between the following: (a) Wildlife sanctuary and biosphere reserve (b) Zoo and wildlife sanctuary (c) Endangered and extinct species (d) Flora and fauna

a) Wildlife sanctuaries are the natural habitats of animals where poaching or capturing of animals is strictly prohibited. Harvesting and other human activities are allowed as long as they don’t interfere with the well-being of animals. Biosphere reserves serve to conserve the biodiversity i.e., plants, animals, microbes as well as the culture of that place. A biosphere reserve consists of many protected areas such as national parks, sanctuaries, and lakes etc.
b) Wildlife sanctuaries are the natural habitats of animals where poaching or capturing of animals is strictly prohibited. Harvesting and other human activities are allowed as long as they don’t interfere with the well-being of animals. Zoos are the artificial habitats of animals wherein animals are conserved for public view. Wildlife sanctuaries cover a large geographical area as compared to that of a zoo.
c) Species with numbers diminished to the level that puts them at the verge of extinction are categorized as endangered species. Protection and conservation of these species are required to ensure their survival. Examples: tiger, wild buffaloes. Extinct species are those which are no longer present on the earth e.g., Dodo.
d) All plant species of an area constitute its flora while its entire animal species makes its fauna.
