Answer 1

One of the ex situ conservation methods for endangered species is cryopreservation.

Explanation:

Ex situ conservation means conserving species outside their natural habitat. Cryopreservation involves preserving gametes, seeds, or embryos at very low temperatures (usually in liquid nitrogen at –196°C). Biosphere reserves, national parks, and wildlife sanctuaries are in situ conservation methods (within natural habitat).
