Hint: Zoological park is a place where various living organisms are kept within enclosures, displayed to the public, and can also be used for study purposes. It is a kind of ex-situ conservation. Here the organisms are protected outside their natural habitat.
Zoological Park is a place where animals are protected under human care. This is the off-site conservation of animals and plants outside their natural habitats. This is particularly important for some endangered species whose habitats are severely degraded or destroyed, the risk from poaching is too high, or the number of surviving individuals is too small to sustain the species. Such species or their DNA which contains their genetic blueprint are conserved by ex-situ methods in Zoos. In the Zoological park, there will be sufficient facilities for maintaining the health and well-being of the animals being protected. There will be a proper medical team for pathological investigation, health, care, etc.
-Ex-situ conservation in zoos and botanical gardens is now a common practice. There are more than 1,500 botanical gardens and arboreta all over the world, with more than eighty thousand species of protected plants.
-There are more than 800 conservation zoos around the world, with more than 3,000 species of animals.
-The other methods of ex-situ conservation includes gene banks, pollen banks, seed banks, tissue culture centers, germplasm banks, cryopreservation centers, etc.
So, the correct answer is option (a) 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
Note: The two basic strategies have been proposed to ensure the future survival of endangered species. They are in situ or onsite conservation and ex-situ or off-site conservation.
-In situ conservation entails the establishment of protected areas of a habitat within which the endangered wild population can stabilize and survive.
-Ex-situ conservation advocates the protection of the populations of species through breeding programs outside their natural habitats.
