Which of the following is an example of an ex situ conservation method?a.National parksb.Seed banksc.Wildlife sanctuariesd.Biosphere reserves

Breakdown of the Problem

We need to identify which option represents an example of ex situ conservation. Ex situ conservation involves the preservation of species outside their natural habitats.

Relevant Concepts

• Ex situ conservation methods typically include practices like storing seeds, breeding animals in controlled environments, or maintaining plants and animals in facilities such as zoos and botanical gardens.
• In situ conservation, on the other hand, refers to protecting species in their natural habitats, which aligns more with national parks, wildlife sanctuaries, and biosphere reserves.

Analysis and Detail

1. National Parks: These areas are designated for the protection of wildlife and natural resources in their natural environment; thus, they are an example of in situ conservation.
2. Seed Banks: Seed banks store seeds outside of their natural habitat for future use. This is a clear example of ex situ conservation.
3. Wildlife Sanctuaries: Similar to national parks, wildlife sanctuaries protect species in their natural environment, representing in situ conservation.
4. Biosphere Reserves: These are areas designated for the conservation of biodiversity and sustainable development, focusing on in situ conservation methods.

Verify and Summarize

Upon reviewing the definitions and examples of each conservation method, only the seed banks fall squarely within the category of ex situ conservation.

Final Answer

b. Seed banks is the correct answer, as they exemplify ex situ conservation methods by preserving genetic materials outside their natural habitats.
