none of these

Explanation:

• The first option describes ecological succession (rebuilding of a community over time), not a disturbance.
• The second option refers to a model of ecosystem change, not a disturbance.
• The third option defines a disturbance as an event that alters a community by affecting organisms or resources, which matches the ecological definition of a disturbance.
