UGC NET Questions (Paper – 1)

Ex situ conservation involves taking components of biodiversity away from their natural settings and maintaining them in artificial or controlled environments. Examples include seed banks,field gene banks,zoos and botanical gardens. The stem describes conservation outside natural habitats in such facilities,which is precisely ex situ conservation. Hence Option B is correct.

Option A:
On farm conservation maintains traditional crop varieties in farmers’ fields under local management. It is not the general approach of gene banks,zoos or botanical gardens described in the stem.

Option B:
Ex situ conservation specifically means conserving biodiversity outside natural habitats in controlled facilities like gene banks,botanical gardens and zoos,matching the stem.

Option C:
In situ conservation protects species within natural ecosystems and protected areas,which is the opposite of “outside their natural habitats.”

Option D:
Landscape conservation focuses on managing larger scale landscapes and habitats; it is not the specific off site facility based approach described here.
