- Population
- Community
- Ecosystem
- Biosphere

2. **Define Each Level**:
- **Organism**: A single living entity.

- **Community**: Different populations of various species that live together in a defined area.
- **Ecosystem**: A community of living organisms interacting with their physical environment (including non-living components like air, water, and soil).
- **Biosphere**: The global sum of all ecosystems; it represents the zone of life on Earth.

3. **Identify the Highest Level**: Among these levels, the biosphere encompasses all ecosystems and is the largest and most inclusive level of biological organization.
