One of the ex situ conservation methods for endangered species is

Options

A. Wild life sanctuaries
B. biosphere reserve
C. Cryopreservation
D. National Park

Answer

**Step-by-Step Text Solution:**

1. **Understanding Conservation Methods:**
- Conservation methods are strategies used to protect and preserve biodiversity, particularly endangered species. There are two main types of conservation: in-situ and ex-situ.

2. **Defining In-situ and Ex-situ Conservation:**
- **In-situ Conservation** refers to the conservation of species in their natural habitats. Examples include wildlife sanctuaries, biosphere reserves, and national parks.
- **Ex-situ Conservation** involves the conservation of species outside their natural habitats. This includes methods such as botanical gardens, zoos, and cryopreservation.

3. **Identifying Ex-situ Conservation Methods:**
- Among the options provided (Wildlife Sanctuary, Biosphere Reserve, Cryopreservation, National Parks), we need to identify which one is an ex-situ conservation method.
- Wildlife sanctuaries, biosphere reserves, and national parks are all examples of in-situ conservation, as they protect species within their natural environments.

4. **Explaining Cryopreservation:**
- Cryopreservation is an ex-situ conservation method that involves storing biological material (like seeds, cells, or tissues) at very low temperatures (around -196 degrees Celsius). This method helps preserve the genetic material and viability of endangered species.

5. **Conclusion:**
- Therefore, the correct answer to the question "One of the ex situ conservation methods for endangered species is" is **Cryopreservation**.
