1.What assumptions does this model make about co-dominance as well as the general terrain of the ecosystem?
Look at the chart, plant A is going up until 10000 quickly, but plant B is going down until zero quickly. So I think the plant A and plant B don't have co-dominance. And they could not live in the same general terrain of the ecosystem.
2.Do you find one producer to be dominant? Why might one producer be dominant over another?
Yes, plant A. Because "survive of the finest.".
Step2
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?
Yes, it does. Yes, it is. Because the herbivores might like plant A more, so plant B has advance.
2.If the simulation included decomposers, how would your current results change?
if the simulation included decomposers, the results change would be more equal field, the line for plant A and plant B would be more closer.
3.How do producer population numbers with the presence of an herbivore compare to the primary colonizer model?
Producer population numbers with the presence of an herbivore is higher the primary colonizer model would be more equal, but if it too high, the primary colonizer model would lost balance. The plant A would go to low.

Step1
1.Was your prediction correct? How did you arrive at your prediction? What differences were there between your prediction and the simulation?
My prediction is all species will survive, but some will decrease and some will increase.
Yes, it was. Run the model twice. The different are top predator and omnivores are almost no changed.
2.What would happen to this imaginary ecosystem if the producers were to die out?
The all ecosystem would die out too.
3.Did any of the species increase in number? What could account for this increase? Which species decreased in number and what might account for this decrease?
Yes, it did. Herbivore A. The account this increase is the Herbivores have big numbers and Omnivores haven't. The top predator eats omnivores. It makes the number of Omnivores lease, and Herbivores would increase because not that much Omnivores eat them.
4.Which populations would benefit the most from the presence of decomposers?
Plants.
Step2
1.Was your prediction correct? How did you arrive at your prediction? What differences were there between your prediction and the simulation?
My prediction is Plant A and Top predator will be increase. All rest will be decrease.
Yes, it was. I run it 100 timesteps. There are no different.
2.Were you able to modify the parameters so that each species survived? Explain how you decided what changes to make.
No, I weren't.
3.Which way does energy flow and how does eating an organism result in energy transfer?
Energy flow is plants to Herbivores to Omnivores to Top Predator. It save in the one eat the others. Then when they are ate, the energy for them will transfer to the one eat them.
