Open Ended

Describe how the timing and duration of a disruption can influence its impact on an ecosystem, using the diagram as a reference.

Multiple Choice

Which of the following best describes the difference between resistance and resilience in species when faced with natural disruptions?

• Resistance is the ability to return to the original state after a disruption, while resilience is being unaffected by the disruption.

• Resistance is being unaffected by the disruption, while resilience is the ability to return to the original state after a disruption.

• Resistance and resilience both mean being unaffected by disruptions.

• Resistance and resilience both refer to the speed of recovery after a disruption.

Multiple Choice

Which of the following best describes 'resilience' in an ecosystem?

• The ability of a species to remain unaffected by a disruption

• The rate at which a species returns to its original state after a disruption

• The removal of non-adapted species by a fire

• The process of adaptation to new environments

Multiple Choice

Multiple Choice

Which of the following statements about natural disruptions and animal migrations is correct?

• All disruptions cause permanent habitat loss.

• Frequent, rapid disruptions always lead to extinction.

• Disruptions can cause large habitat changes and animal migrations.

• Resistance and resilience have no effect on ecosystem recovery.

Open Ended

How can long, rare natural disruptions impact ecosystems compared to frequent, rapid disruptions?

Open Ended

How can long, rare natural disruptions affect animal migrations and habitats?

Multiple Choice

According to the intermediate disturbance hypothesis, what effect do intermediate levels of disturbance have on an ecosystem?

• They decrease species diversity due to constant stress.

• They increase species diversity by building resistance and resilience.

• They have no effect on species diversity.

• They cause extinction of most species.

Open Ended

Explain how natural disruptions can be both beneficial and harmful to ecosystems, using examples from the slides.

Multiple Select

Which of the following are possible reasons for animal migration as discussed in the slides?

• To find more abundant resources

• To escape from predators

• To find mates

• To move to areas with more favorable conditions

Multiple Choice

According to the intermediate disturbance hypothesis, what is the effect of intermediate levels of disturbance on ecosystem diversity?

• It decreases diversity due to constant change.

• It increases diversity due to the build up of resistance and resilience.

• It has no effect on diversity.

• It causes extinction of most species.
