Question

Which one of the following is not used for ex situ plant conservation?

• A. Botanical gardens
• B. Shifting cultivation
• C. Seed banks
• D. Field gene banks

Answer 1

The correct option is B Shifting cultivation

Ex-situ conservation is protecting an endangered species, variety or breed of plant or animal outside its natural habitat.

Botanical gardens, field gene banks and seed banks are examples of ex-situ conservation.

Botanical gardens have a collection of living plants for reference.

Seed banks store seeds as a source of germplasm, in case seed reserves elsewhere are destroyed.

Field gene banks preserve the genetic material of the organisms.

Shifting cultivation is an agricultural system in which a piece of land is used for agriculture for a short period of time and then the land is abandoned. It leads to deforestation.

So, the correct answer is option C.
