Protected areas are an extremely important part of programs to conserve biodiversity and ecosystems, especially for sensitive ha
bitats. There are two methods of biodiversity conservation: in-situ (natural home) or ex-situ (artificial home). All BUT ONE is an example of an in-situ method of conservation. That is a A) national park. B) botanical garden. C) wildlife preserve. D) wildlife sanctuary.
Ex-situ conservation is a process of preservation of biological diversity outside their natural habitats. It includes conservation of genetic as well as wild species living in that area.
Except, botanical garden rest all are the example of an in-situ method of conservation, which involves conservation of species in their natural or similar environment.
The one that is not an example of insitu protection is the botanical garden since the three others, ie national park, wildlife sanctuary and wildlife preserve are definitely insitu types because they result from simply designating areas that already exist naturally so that the animals and plants can live in a sense, at home.
When a scientific experiment is carried out in a controlled setting, all variables are kept the same except for the C. experimental. Experimental variables are the things you are studying in the experiment and it is the only variable you can change.
