What is meant by the term " Red Data Book " , " biosphere " And " national park " . Give examples of each. (thumbs up for the best answer)

the IUCN (international union for conservation of nature and natural resources ) publishes a catalouge which lists the species that are rare and under the threat of extinction . it is known as red data book .some of the species listed here are bengal tiger , sea turtle etc.

if u mean biosphere then it is a narrow zone of  contact between the atmosphere , hydrosphere and lithosphere but if u mean biosphere reserves , then it means an  a specified land area in which land can be used for various purposes or  an area of land or water protected by law to support the conservation of ecosystems .

for example, the Cold Desert of Himachal Pradesh serves as a biosphere reserve

A national park is a reserve of natural, semi-natural, or developed land that a sovereign state declares or owns. It is most commonly a natural park .

for example , ranthambore national park and kaziranga national park in assam.
