Ecosystem Dynamics and Prairie Analysis

The video tutorial explores a prairie ecosystem through a simulation. It guides students to download a graphic organizer and observe population dynamics by altering grass levels. The tutorial examines changes over two and twenty years, focusing on equilibrium. It concludes with an analysis of a fire's impact on the ecosystem.

What is the primary focus of the video tutorial?

• A marine ecosystem

• A desert ecosystem

• A prairie ecosystem

• A forest ecosystem

What tool is suggested for organizing information about the prairie ecosystem?

• A spreadsheet

• A notebook

• A graphic organizer

• A presentation slide

What is the limitation of the free account in the simulation?

• It allows only 10 minutes of access

• It provides limited data

• It allows only 5 minutes of access

• It has no access to graphs

What is the initial population focus in Activity A?

• Foxes

• Prairie dogs

• Grasshoppers

• Ferrets

What change is made to the grass in the simulation?

• Increased by 50%

• Left unchanged

• Doubled

• Reduced by 50%

What is observed in the prairie ecosystem after two years?

• All populations increased

• No change in populations

• All populations decreased

• Some populations increased, others decreased

What does the line graph in the simulation show?

• Water availability

• Changes in weather patterns

• Population changes over time

• Soil quality variations

What is meant by 'equilibrium' in the context of the ecosystem?

• A state of decline

• A balanced state

• A state of growth

• A state of constant change

What hypothetical scenario is discussed at the end of the video?

• A flood

• A drought

• A fire

• An earthquake

What is the expected long-term result of a fire in the prairie?

• Gradual recovery

• Immediate recovery

• Permanent damage

• No effect
