Step 1
  1. What assumptions does this model make about co-dominance as well as the general terrain of the ecosystem?  I assume that these two plants do not coexist well together.  One dominated with 10,000 plants while the other one ended up with zero.
  2. Do you find one producer to be dominant? Why might one producer be dominant over another?   I found that Plant A overtook Plant B.  I think that the rate at which is reproduces could have affected the other plants' space to reproduce.

Step 2
  1. Does adding the herbivore establish a more equal field? Is one producer still dominant over the other? Why might one producer be dominant over another?  When you add a herbivore which eats the dominant plant, it will allow Plant A and Plant B to be more equal.  Plant B is now more dominant than Plant A now.  Since no one is harming Plant B, it can reproduce freely.
  2. If the simulation included decomposers, how would your current results change?  I think that there will more of each plants because the decomposers make the soil fertile.  With the soil fertile, the plants can reproduce even more,
  3. How do producer population numbers with the presence of an herbivore compare to the primary colonizer model? It averaged out the number of plants between Plant A and Plant B.
