Predator-Prey Simulation ActivityPg. 49 activity 1-2C

Rules:• Prey and predators must stand 0.5 m back to habitat• If half of more of prey is covered by predator, the

prey has been CAPTURED and is removed• In each round, a predator MUST capture 3 prey to

survive• If fewer than 3 prey caught, predator DIES• Each predator that captures 3 prey lives to reproduce

one new offspring (3 prey=1 new predator)• If ALL predators die, new predator enters habitat• Prey population DOUBLES each generation (i.e. if 10

survive20 next round)• Maximum carrying capacity of habitat is 200 prey
