What is Ex Situ and In Situ Conservation

Conservation of biological diversity is crucial for maintaining essential ecological diversity and preserving the continuity of food chains. There are two modes of Conservation of biodiversity as follows: (a) Ex-situ Conservation: Involves protecting threatened species outside their natural habitat, e.g., zoos, botanical gardens, and seed banks.
(b) In-situ Conservation: On-site conservation within natural populations of plant or animal species, e.g., national parks, sanctuaries, and reserved forests.
