Predator-Prey Dynamics Quiz

What is the primary relationship between predators and prey?

• Predators and prey are independent of each other.

• Predators eat prey, and prey eat predators.

• Predators kill and eat prey, while prey are the organisms that get eaten.

• Predators and prey have no effect on each other's populations.

On a predator-prey graph, what does the y-axis typically represent?

• Number of organisms

• Time

• Types of species

• Environmental conditions

What happens to prey populations when conditions are ideal?

• They remain constant.

• They become extinct.

• They decrease rapidly.

• They increase until reaching carrying capacity.

What is the carrying capacity in the context of prey populations?

• The average number of prey in a habitat.

• The minimum number of prey needed for predators to survive.

• The maximum number of prey a habitat can support.

• The maximum number of predators a habitat can support.

How does an increase in prey population affect predator population?

• It causes the predator population to decrease.

• It causes predators to migrate.

• It leads to an increase in predator population.

• It has no effect on the predator population.

What happens to the predator population when the prey population decreases?

• The predator population increases.

• The predator population becomes extinct.

• The predator population decreases.

• The predator population remains constant.

Why is there typically more prey than predators in an ecosystem?

• Because predators reproduce faster than prey.

• Because energy flow through the ecosystem is inefficient.

• Because prey are more intelligent than predators.

• Because predators are less adaptable.

What is a key observation about the predator-prey graph?

• The predator curve lags behind the prey curve.

• The prey curve is always higher than the predator curve.

• The predator and prey curves are identical.

• The predator curve leads the prey curve.

What is a limitation of the predator-prey model discussed?

• It assumes prey populations never recover.

• It assumes predators are always successful in hunting.

• It assumes prey can never escape predators.

• It assumes predators only eat one type of prey.

What is a common pattern observed in both predator and prey populations?

• They both increase steadily.

• They both decrease steadily.

• They both experience booms and busts.

• They both remain constant over time.
