Explanation:

 situ conservation is on-site conservation of genetic resources in natural populations of plant or animal species. It is the process of protecting an endangered plant or animal species in its natural habitat, either by protecting or cleaning up the habitat itself, or by defending the species from predators. National parks, wildlife sanctuaries, biosphere reserves etc. are its examples. Ex-situ conservation is the process of protecting an endangered species of plant or animal outside its natural habitat; for example, by removing part of the population from a threatened habitat and placing it in a new location. Botanical Gardens, Zoological Parks, germplasm banks are its examples.
