Population and Natural Selection

Dive into the world of population dynamics and natural selection in this interactive survival simulation game. Explore the model ecosystem of rabbits, coyotes, and vegetation where survival depends on strategic choices. Observe the impact of camouflage, food availability, and predator-prey interactions. Record and graph data to analyze population trends and adaptation over time.

  1. Population and Natural Selection

  2. Food Chain

  3. Studying Populations: Who will survive?

  4. The Model

  5. Rabbit (Bean) Coyote (Cardboard) • Eats vegetation (rice) • Needs to eat one carrot each round to survive • Camouflages to avoid being eaten • Eats rabbits • Needs to eat two rabbits each round to survive • Moves faster to catch enough rabbits

  6. Survival 1- Level 1 coyotes will leave one of the available rabbits 2- Level 2 coyotes will leave two of the available rabbits 3- Level 3 coyotes will leave four of the available rabbits, but they can eat red camouflaged rabbits White rabbits camouflage on white and pink spaces Red rabbits camouflage on red and pink spaces Black rabbits camouflage on black spaces Each round, coyotes will randomly eat up to fourrabbits if they can, and the remaining rabbits will each eat one carrot if available. If there isn’t enough food for a particular animal, they starve and die. After eating/dying, animals reproduce themselves. Each surviving animal makes one new copy of itself (doubles). Add 3 new plants to each space. Randomly redistribute animals to spaces. If populations go extinct in one area, have other animals migrate from neighboring areas.

  7. Examples 1- Level 1 coyotes will leave one of the available rabbits 2 Red rabbits are visible on the white space 1 Black rabbit is visible on one of the pink spaces Coyote randomly eats two of the visible rabbits, leaving one. Remaining 6 rabbits eat 1 carrot each Populations double, add 3 new carrots to each space

  8. Record and graph data
