To solve the question regarding cryopreservation, seed bank, gene bank, and wild safari parks, we need to determine what these methods represent in the context of biodiversity conservation.
### Step-by-Step Solution:
1. **Understanding the Terms**:
- **Cryopreservation**: This is the process of preserving cells, tissues, or any other substances containing living organisms by cooling them to very low temperatures (typically using liquid nitrogen at -196 degrees Celsius). This method is used to store genetic material and living cells for future use.
- **Seed Bank**: A seed bank is a facility that stores seeds of various plant species to preserve genetic diversity. Seeds are kept in controlled conditions to ensure their viability for long periods.
- **Gene Bank**: Similar to seed banks, gene banks preserve genetic material, including DNA, sperm, and embryos from various species. This helps in the conservation of genetic diversity.
- **Wild Safari Parks**: These are protected areas where wild animals are kept in conditions that mimic their natural habitat, allowing for conservation and education.
2. **Identifying the Conservation Method**:
- All the mentioned methods (cryopreservation, seed banks, gene banks, and wild safari parks) involve the preservation of living organisms but do so outside their natural habitats. This is known as **ex-situ conservation**.
- In contrast, **in-situ conservation** refers to the conservation of species in their natural habitats, which is not the case for the methods listed.
3. **Conclusion**:
- Since all these methods involve the preservation of biodiversity outside of natural ecosystems, they are categorized under **ex-situ conservation**.
### Final Answer:
Cryopreservation, seed bank, gene bank, and wild safari parks are methods of **ex-situ conservation**.
