Ecosystem Resilience and Disturbances

Mrs. Ciccone discusses resilience, focusing on how life and ecosystems recover from disturbances. She explains ecological resilience, the ability of ecosystems to return to normal after disruptions. Using a bowl and marbles analogy, she illustrates how ecosystems adapt to changing conditions and disturbances like fire, flood, and pollution. The video concludes with the idea that significant changes can lead to a new normal in ecosystems.

What does it mean for a person to be resilient?

• They never face any challenges.

• They rely on others for support.

• They can quickly return to normal after difficulties.

• They avoid all risks.

How is ecological resilience defined?

• The ability of an ecosystem to remain unchanged.

• The ability of an ecosystem to recover quickly after disturbances.

• The ability of an ecosystem to expand rapidly.

• The ability of an ecosystem to resist all changes.

What does the bowl represent in the analogy used to explain ecosystems?

• The disturbances affecting an ecosystem.

• The living organisms in an ecosystem.

• The abiotic components of an ecosystem.

• The stability and conditions of an ecosystem.

Which of the following is NOT a disturbance that can affect an ecosystem?

What happens when the variables in an ecosystem change too much?
