State the approaches for the conservation of biodiversity.

(N/A) There are two main approaches for the conservation of biodiversity:
$(a)$ $In-situ$ conservation
$(b)$ $Ex-situ$ conservation
When we conserve and protect the whole ecosystem,its biodiversity at all levels is protected. For example,to save the tiger,we must save the entire forest; this is called $In-situ$ conservation.
In situations where an animal or plant is endangered and needs urgent measures to save it from extinction,$Ex-situ$ conservation is the appropriate approach.
