This model simulates predation interaction and the patterns of population changes over time.
Grades: 6-8;
Embedded Files
Agents:
Agents:
There are three types of agents: plants, rabbits, and foxes.
Model Rules:
Model Rules:
There are 168 patches (light blue squares) in the model. The nutrients in each patch may support and only support one plant.
Rabbits feed on plants; foxes prey on rabbits; plants regrow every year.
Foxes and rabbits lose energy when they move around to search for food and die when running out of energy.
Foxes and rabbits gain energy when they find food and will produce offspring when they accumulate enough energy.
THINGS TO TRY
What population patterns emerge when only plants and rabbits are present in the model?
What population patterns emerge when only plants and foxes mouse species are present in the model?
What population patterns emerge when only rabbits and foxes mouse species are present in the model?
What population patterns emerge when all three species are present in the model?
How does plant growth rate affect the interactions among the three species?
