Lessons > The Producers > Step 1

Imagine the ecosystem is newly forming—the previous ecosystem has been destroyed by fire or flood—and the first colonizers of the successive ecosystem are, of course, producers. Given the two fictitious species of plants in the simulator, predict what will happen in this young system and record your prediction in the Data Table. Then run the simulator to 100 time steps and record the population numbers for both plants. Answer the following:

1. What assumptions does this model make about co-dominance as well as the general terrain of the ecosystem?
2. Do you find one producer to be dominant? Why might one producer be dominant over another?
