2. **Analyzing the Options**: The options provided include:
- Greenhouse effect
- Biological control
- Biosphere balancing

3. **Evaluating Each Option**:
- **Greenhouse Effect**: This is a natural process that warms the Earth but is not a service that helps preserve ecosystems. Instead, it can lead to adverse effects like global warming.
- **Biological Control**: This refers to using natural predators or biological methods to control pests in agriculture. While beneficial, it is a specific method rather than a broad service provided by nature.
- **Biosphere Balancing**: This involves maintaining the balance between biotic (living) and abiotic (non-living) components of the ecosystem. However, it is not a term that directly refers to the services provided by nature.
