Which of the following is not an example of in situ conservation?

When we conserve and protect the whole ecosystem, its biodiversity is protected at all levels. This approach is called in-situ (on site) conservation. Biodiversity hotspots, biosphere reserves, national parks, wildlife sanctuaries, and sacred grooves are all examples of in-situ conservation.

Ex-situ conservation is when threatened animals and plants are taken out from their natural habitat and placed in a special setting where they can be protected and given special care. Zoological parks, botanical gardens, and wildlife safari parks serve this purpose. In recent years, ex situ conservation has advanced beyond keeping threatened species in enclosures. Now, gametes of threatened species can be preserved in viable and fertile conditions for long periods using cryopreservation techniques. Eggs can be fertilized in-vitro, and plants can be propagated using tissue culture methods. Seeds of different genetic strains of commercially important plants can be kept for long periods in seed banks.
