    Out of in situ or ex situ conservation, which type of conservation measures help the larger number of species to survive? Explain in detail.

    Answer:

    In situ is on - site conservation, which implies that species are conserved in their natural habitat, while ex situ conservation implies conservation of genetic resources and different organisms outside their natural habitat. To conserve species in their natural habitat, the entire ecosystem has to be conserved, which includes other organisms, biotic and abiotic components of the ecosystem associated with the target species. In situ conservation helps in the restoration of degraded ecosystems and habitats. These are means of conserving genetic resources, species, ecosystems and landscapes without uprooting the local people. They ensure culturally, socially and ecologically sustainable economic development. Hence, in situ conservation helps in the survival of larger number of species.
