Question

The type of conservation in which the threatened species are taken out from their natural habitat and placed in special setting where they can be protected and given special care is called:

A

Ex Situ Conservation

B

Semi-conservative method

C

Sustainable development

D

In-situ conservation

Step-by-Step Solution

, ex-situ (off-site) conservation is the specific approach where threatened animals and plants are taken out from their natural habitat and placed in special settings where they can be protected and given special care , . This method is used when an organism is endangered or threatened and requires urgent measures to save it from extinction . Examples of this approach include zoological parks, botanical gardens, and wildlife safari parks , . In contrast, in-situ (on-site) conservation involves protecting the whole ecosystem so that the species is protected within its natural habitat , . While 'Ex-situ' is the precise term defined in the text, it is not included in the provided options; 'In-situ' represents the opposite approach, and 'semi-conservative' refers to DNA replication rather than species conservation , .
