Question

An example of ex-situ conservation is
A. National park
B. Seed bank
C. Wildlife sanctuary
D. Sacred Grove

Answer 1

Hint: Ex situ conservation means conservation outside the habitats by making zoos, gardens etc. Ex-situ conservation is the process of protecting an endangered species, plants and animals outside its natural habitat by simply removing part of population from a threatened habitat and placing it in a new location.

Complete step by step answer:
Advantages of ex-situ conservation are:
1. It helps in control of essential conditions such as climate control, dietary intake, veterinary care etc.
2. Improves the chances of successful breeding with the help of artificial methods like IVF and embryo transfer.
3. Cryopreservation is the ex-situ method for plants. It involves the storage of seeds, pollen or embryos in liquid nitrogen.
4. Conservation of livestock genetics can also be done with the help of cryopreservation.
5. Cryopreservation is used for indefinite storage of material over a much greater time period.
6. The conservation of ecosystems and natural habitats and the recovery of viable populations of species in their natural surroundings is called situ conservation.
7. Seed bank stores seeds to preserve the genetic diversity thus, it is a type of gene bank. It is an ex situ conservation method. It is a type of gene bank.
The correct answer is Seed bank.

So, the correct answer is “Option B”.

Note:
Ex-situ techniques are costly, cryogenic storage is economically infeasible because species stored in this manner may slowly drain the financial resources of the organization. But the maintenance of species is required for the sustainable growth and development.
