- The biosphere is a global ecological system that integrates all living beings and their relationships with the environment. It includes all ecosystems on Earth.

2. **Analyzing the Options:**
- **Option A: Plants of the world** - This option is too narrow as the biosphere includes not just plants but all forms of life.
