The correct Answer is:
To solve the question, we need to analyze the given statements about "X" and determine what "X" represents based on the characteristics described. ### Step-by-Step Solution: 1. **Analyze Statement I**: - "X" should not show too much variation in productivity from year to year. - This suggests that "X" is a stable entity, likely referring to a community or ecosystem that maintains consistent productivity over time. 2. **Analyze Statement II**: - "X" must be either resistant or resilient to occasional disturbances. - This indicates that "X" can withstand or recover from disturbances, which is a characteristic of stable ecosystems or communities. 3. **Analyze Statement III**: - "X" must also be resistant to invasions by alien species. - This implies that "X" has mechanisms to prevent or mitigate the impact of invasive species, which is another characteristic of a stable ecosystem. 4. **Conclusion**: - Based on the analysis of the three statements, "X" is likely referring to a "stable community" or "climax community." These communities are characterized by stability, resilience to disturbances, and resistance to invasive species. 5. **Final Answer**: - Therefore, "X" stands for a **stable community**.
