The correct Answer is:
To determine the characters of a stable community, let's analyze each option provided in the question: 1. **Option A: It shall not show too much variation in year-to-year productivity.** - A stable community typically exhibits consistent productivity levels over time. This means that the community can maintain its structure and function without significant fluctuations in productivity, which is a hallmark of stability. 2. **Option B: It must be either resistant or resilient to seasonal disturbance.** - Stability in a community often involves its ability to withstand or recover from disturbances. A stable community should either resist disturbances (e.g., droughts, floods) or be resilient enough to bounce back after such events. This characteristic is crucial for maintaining ecological balance. 3. **Option C: It must be resistant to invasion by alien species.** - A stable community is generally less susceptible to invasions by non-native species. Resistance to such invasions helps preserve the native biodiversity and ecological integrity of the community, contributing to its overall stability. 4. **Option D: None.** - This option suggests that none of the previous statements are true regarding the characteristics of a stable community. **Conclusion:** Based on the analysis, options A, B, and C all describe important characteristics of a stable community. Therefore, the correct answer would be that options A, B, and C are indeed characteristics of a stable community. ### Step-by-Step Solution: 1. **Analyze Option A**: Identify that stability involves consistent productivity. 2. **Analyze Option B**: Recognize the importance of resistance or resilience to disturbances. 3. **Analyze Option C**: Understand that resistance to alien species is crucial for stability. 4. **Evaluate Option D**: Conclude that options A, B, and C are valid characteristics of a stable community.
