1. **Understanding Biosphere Reserves**: A biosphere reserve is a protected area designated by UNESCO to promote sustainable development and conservation of biodiversity. It typically consists of various zones that serve different purposes.

2. **Identifying the Zones**: Each biosphere reserve is divided into three distinct zones:
- **Core Zone**: This is the innermost area, where human activities are highly restricted to protect the biodiversity and ecosystems. It is primarily for conservation purposes.
- **Buffer Zone**: Surrounding the core zone, this area allows for some human activities that are compatible with conservation. It serves as a protective barrier for the core zone.
- **Transition Zone**: This is the outermost area where human settlements and activities are permitted. It is designed for sustainable development and resource management.

3. **Conclusion**: Therefore, each biosphere reserve consists of **three zones**: Core Zone, Buffer Zone, and Transition Zone.
