Which of the following is a key way ecosystems naturally control animal populations?

• Prey populations always remain stable regardless of predator numbers

• Predator-prey relationships regulate population sizes over time

• Species adapt by evolving to avoid being eaten entirely

• Animal populations are controlled mainly by human intervention
