Question

Which of the following is not a method of ex situ conservation?

• A. In vitro fertilization
• B. National Parks
• C. Micropropagation
• D. Cryopreservation

Answer 1

The Correct Option is B

National parks serve as a means of conserving biodiversity in situ by providing protection for organisms within their natural habitats. National Parks is not a method of ex situ conservation.

Ex situ conservation refers to the conservation of species outside their natural habitats. It involves the removal of plants, animals, or microorganisms from their original ecosystems and placing them in controlled environments. The primary objective is to protect and preserve endangered species and genetic diversity.

Among the options provided, National Parks does not fall under ex situ conservation. National Parks are designated protected areas within a country's boundaries that aim to conserve ecosystems, biodiversity, and natural resources in their original habitats (in situ conservation). National Parks typically focus on the preservation of ecosystems and their associated flora and fauna within their natural settings, rather than removing species from those habitats.

On the other hand, the other options listed are methods of ex situ conservation:

• In vitro fertilization: Involves the fertilization of eggs outside the organism's body to aid reproduction and preserve genetic diversity.
• Micropropagation: Involves the propagation of plants using tissue culture techniques to produce multiple genetically identical plants from a small tissue sample.
• Cryopreservation: The process of preserving biological material, such as seeds, embryos, or tissues, at extremely low temperatures to maintain their viability for future use.

Therefore, National Parks is the option that does not belong to ex situ conservation methods.
