After a Large-Scale Disturbance,such as a Volcanic Eruption or a Major

Question

After a large-scale disturbance,such as a volcanic eruption or a major hurricane,
A) all disturbed systems will eventually return to their original states.
B) some disturbed systems will recover,but most will suffer extinction.
C) some disturbed systems will recover,but only with the help of restoration ecology.
D) some disturbed systems will recover,while severely disturbed ones will undergo ecological transition to a different system.
E) most disturbed systems will recover and function normally,but they will have very low species diversity.

Accepted Answer

After a large-scale disturbance, some disturbed systems will recover while severely disturbed ones will undergo ecological transition to a different system. This is because the extent of the disturbance determines the degree of change in the system, and it may become a different ecological system altogether. Restoration ecology may be necessary to facilitate the recovery of some systems. Option A is incorrect because not all disturbed systems will return to their original states. Option B is too extreme and not always the case. Option C is partially correct but not all systems require restoration. Option E is incorrect because recovery may result in the restoration of high species diversity.
