Final answer:
Communities may exhibit resistance, resilience, or switch between alternative stable states in response to disturbance.
Step-by-step explanation:
Resistance and resilience are two parameters used to measure changes in ecosystems in response to disturbances. Resistance is the ability of an ecosystem to remain at equilibrium despite disturbances, while resilience is the speed at which an ecosystem recovers equilibrium after being disturbed. Communities may exhibit resistance, resilience, or switch between alternative stable states in response to disturbance. It is not true that communities always respond with resistance or that communities only respond with resilience. Additionally, it is false that communities do not respond to disturbance or that communities always switch between alternative stable states.
