• A snake preying on a mouse

How does predation affect the population dynamics of an ecosystem?

• It decreases the prey population and increases the predator population.

• It increases both prey and predator populations.

• It stabilizes the prey population while decreasing the predator population.

• It has no effect on population dynamics.

Which of the following scenarios best illustrates competition among species?

• Two species of birds feeding on the same type of seeds in a forest.

• A wolf pack hunting a deer.

• A bee pollinating a flower.

• A fish cleaning parasites off a larger fish.

How does competition among species influence biodiversity in an ecosystem?

• It decreases biodiversity by eliminating weaker species.

• It increases biodiversity by promoting species adaptation.

• It has no effect on biodiversity.

• It stabilizes biodiversity by maintaining species balance.

Which of the following is a characteristic of a predator-prey relationship?
