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

In the context of conservation biology, "ex situ conservation" refers to protecting an endangered species outside its natural habitat. This involves efforts like creating controlled environments to maintain and propagate species.

• In vitro fertilization: A technique commonly used for reproducing plants or animals outside their natural environment. This is an ex situ method.
• National Parks: These are protected areas designated for wildlife conservation but occur within the natural habitats of the species. Thus, they are considered in situ conservation, not ex situ.
• Micropropagation: This is a tissue culture method used to grow large numbers of plants from small tissue pieces, an ex situ conservation technique.
• Cryopreservation: This involves freezing biological material at extreme temperatures to ensure longevity and maintain viability outside the natural environment, making it an ex situ method.

Hence, the answer is: National Parks, as they represent in situ rather than ex situ conservation.
