Dynamics of Predator and Prey Populations

What is the primary focus of predator-prey interactions?

• Migration patterns of prey

• Feedback loops between different populations

• Population control within ecosystems

• Nutritional benefits for the predator

What happens to the predator population when prey is abundant?

• It decreases due to competition

• It increases as food is readily available

• It migrates to new areas

• It remains stable

What does a low predator population indicate for the prey?

• Increased risk of being hunted

• Decreased food sources for prey

• Increased chances of prey population growth

• Stable ecosystem with no changes

What triggers a decrease in the predator population within the cycle?

• An increase in prey population

• A decrease in prey population

• Predator migration

• Changes in the ecosystem

Why does the predator population start to decrease after a certain point?

• Because of disease within the predator population

• Because of changes in the weather

• Due to migration of the prey

• Due to overhunting and reduced prey availability

How can the predator-prey cycle be demonstrated?

• Through direct observation only

• Through genetic analysis of predators and prey

• Using computer simulations and observational data

• By studying predator behavior in isolation

What role do computer simulations play in studying predator-prey cycles?

• They help visualize and predict cycle patterns

• They provide a hypothetical view without real data

• They replace the need for real-world data

• They are used for genetic analysis

What evidence supports the predator-prey cycle concept?

• Fossil records

• Predator-only behavior studies

• Computer simulations and observational data

• DNA analysis

Which animals are cited as a real-world example of the predator-prey cycle?

• Snowshoe hare and Canadian lynx

• Lions and zebras

• Sharks and seals

• Wolves and deer

What is the outcome when the predator population is high?

• The predator population migrates

• The prey population decreases

• The ecosystem collapses

• The prey population increases
