Which of the following statements accurately describes the difference between ex situ and in situ conservation, and the situations in which they are applied?
| 1. | Ex situ conservation involves protecting species within their natural habitats, while in situ conservation involves removing species to special facilities; ex situ is used when species are not immediately threatened, and in situ is used for critically endangered species. |
| 2. | In situ conservation involves protecting species in their natural habitats, while ex situ conservation involves conserving species in controlled environments like zoos or botanical gardens; in situ is used for broad ecosystem conservation, whereas ex situ is applied when a species is critically endangered and requires immediate, targeted protection. |
| 3. | Ex situ conservation and in situ conservation both involve protecting species within their natural habitats; both methods are used interchangeably for endangered species. |
| 4. | In situ conservation involves controlled environments like seed banks or zoological parks, while ex situ conservation is focused on protecting species in the wild; ex situ is used for all species under threat of extinction, and in situ for less vulnerable species. |
