A biosphere reserve preserves

Options

A. wild populations
B. traditional life styles of tribals
C. genetic resources of organisms
D. all of above

Answer

**Step-by-Step Solution:**

1. **Understanding Biosphere Reserves**:
- A biosphere reserve is a protected area designated for the conservation of biodiversity, which includes various species of plants and animals. It aims to promote sustainable development and conservation efforts.

2. **Components of Biosphere Reserves**:
- Biosphere reserves consist of three main zones:
- **Core Zone**: This is the innermost area, strictly protected for wildlife and biodiversity. Human activities are not permitted here.
- **Buffer Zone**: Surrounding the core zone, this area allows for limited human activities, such as research and education, while still focusing on the protection of biodiversity.
- **Transition Area**: This is the outermost zone where human settlements and traditional lifestyles can coexist with nature. It supports the livelihoods of local communities, including tribal groups.

3. **Biodiversity Preservation**:
- Biosphere reserves play a critical role in preserving:
- **Wild Populations**: The core zone is dedicated to protecting wild animal populations.
- **Traditional Lifestyles of Tribals**: The transition area allows for the preservation of the cultural and traditional practices of local tribal communities.
- **Genetic Resources of Organisms**: The overall biodiversity, including genetic diversity among species, is preserved across all zones.

4. **Conclusion**:
- Given the roles of biosphere reserves in preserving wild populations, traditional lifestyles of tribals, and genetic resources of organisms, the correct answer to the question is that a biosphere reserve preserves **all of the above** elements.

**Final Answer**: A biosphere reserve preserves all of the elements mentioned: wild populations, traditional lifestyles of tribals, and genetic resources of organisms.
