Question

An example of ex situ conservation is
a. Seed Bank
b. Wildlife Sanctuary
c. Sacred Grove
d. National Park

Answer 1

Ex-situ conservation is the method of conservation of all levels of biological diversity outside their natural habitats through various techniques. The rate to which humans manage or modify the natural dynamics of the managed population varies extensively, and this may include modification of living environments and defense from predation and mortality.

Complete answer:
Ex-situ conservation denotes "off-site conservation". It is the process of protecting an endangered species of plant or animal outside of its natural habitat; e.g., by excluding part of the population from an endangered habitat and placing it in a fresh location, which may be a wild area or in the care of humans. While ex situ conservation includes some of the oldest and best-recognized conservation methods. The seed bank is also an example of ex-situ conservation.

The reason to store seeds is to safeguard the genes that plant breeders require to increase yield, illness resistance, drought tolerance, dietary quality, taste, etc.

A wildlife sanctuary is a place of shelter where ill-treated, injured, and abandoned captive wildlife may live in peace and self-esteem for the remains of their lives.

Sacred groves are any grove of trees that are of special religious significance to a particular culture. A national park is used for protection purposes, created and guarded by national governments.

Hence, the correct answer is option (A).

Note: Ex-situ management can happen within or outside a species' normal geographic range. Individuals preserved ex-situ exist outside an ecological niche. This means that they are not under the same selection pressures as wild populations, and they may experience artificial selection if maintained ex-situ for several generations. Agricultural biodiversity is also preserved in ex-situ collections.
