M3.L4.A2 - Extension example with tumbleweeds

The base model of a simple ecosystem with rabbits, grass, and a predator has been expanded here to add an invasive species -- tumbleweeds, which compete with the grass. The tumbleweeds and grass sprout at the same rate. The rabbits eat the tumbleweeds but only gain half the energy they would receive from eating the grass, and the tumbleweeds crowd out the grass.
