Question
Which of the following is the definition of a disturbance in an ecosystem?
- Any change that causes a disruption in an ecosystem
- When an ecosystem is in a state of balance
- When an ecosystem is no longer in a state of balance and cannot recover
- When an ecosystem changes into a new ecosystem
Hint:
A distrubance in an ecosystem is any change that causes a disruption in an ecosystem.
The correct answer is: When an ecosystem is no longer in a state of balance and cannot recover
An ecological disturbance is an event of biological or nonbiological origin that brings about mortality to organisms and changes in their spatial patterning in their ecosystem. The change an ecosystem experiences as it recovers from a disturbance depends on the intensity and magnitude of the disturbance.
Hence, a disturbance in an ecosystem is any change that causes a disruption in an ecosystem.
