• There were no predators

• There were enough producers for the hare to eat

• The hares had reached their carrying capacity

• There was not enough space for the hares

How does the population of lynx change in response to the hare population?

• Increases as hare population increases

• Decreases as hare population increases

• Remains constant regardless of hare population

• Fluctuates independently of hare population
