Question

5 which of these can help organisms survive a disruption of their ecosystem? a an imbalance between predators and prey b dependence on only one food source c migration to a similar environment d a surplus of predators and prey

Explanation:

• Option A: 捕食者和猎物失衡（an imbalance between predators and prey）会破坏生态系统稳定，不利于生物生存，排除。
• Option B: 只依赖一种食物来源（dependence on only one food source），生态系统受干扰时该食物来源可能受影响，生物易因食物短缺死亡，排除。
• Option C: 迁徙到相似环境（migration to a similar environment），生态系统受干扰后，生物到相似环境能获得适宜生存条件（如食物、栖息地等），有助于生存。
• Option D: 捕食者和猎物的减少（a decrease of predators and prey）会破坏食物链和生态平衡，不利于生物生存，排除。

Answer:

C. migration to a similar environment
