Which statement best describes ecological resilience?

• A. Resilience is the ability to recover after disturbance or adapt to change.
• B. Stability refers to the tendency to return to a steady state with small fluctuations.
• C. Resilience means staying constant with no changes.
• D. Stability means adaptation.

Answer: (A)

Ecological resilience is about how an ecosystem handles disturbances and keeps functioning. It isn’t just about staying the same; it’s about the ability to recover after a disturbance or to adapt to changing conditions, so the system can continue providing its essential services.

That’s why the statement describing resilience as the ability to recover after disturbance or adapt to change is the best fit. After events like fires, floods, or droughts, a resilient ecosystem can bounce back, regrow, or reorganize in a way that maintains its structure and function. It also encompasses adapting to new conditions, such as climate shifts that alter species composition or interactions, while still meeting its ecological roles.

Saying resilience equals staying constant with no changes or that stability means adaptation can be misleading. Stability focuses on returning to a particular steady state with small fluctuations, which isn’t the same as coping with larger disturbances or reorganizing after changes. And while adaptation can be part of resilience, resilience specifically emphasizes that recovery and reorganization in the face of disruption, not just the act of staying constant or simply adjusting.
