Responses to questions
Step 1:
What assumptions does this model make about co-dominance as well as the general terrain of the ecosystem?
Do you find one producer to be dominant? Why might one producer be dominant over another?
Step 2:
Do you find one producer to be dominant? Why might one producer be dominant over another?
How do producer population numbers with the presence of an herbivore compare to the primary colonizer model?

Responses to questions
Step 1:
Was your prediction correct? How did you arrive at your prediction? What differences were there between your prediction and the simulation?
What would happen to this imaginary ecosystem if the producers were to die out?
Which populations would benefit the most from the presence of decomposers?
Step 2:
Was your prediction correct? How did you arrive at your prediction? What differences were there between your prediction and the simulation?
Were you able to modify the parameters so that each species survived? Explain how you decided what changes to make.

Explanation / Answer
Q- Which way does energy flow and how does eating an organism result in energy transfer?
A - Energy flows in a unidirectional- forward way, from one trophic level to another. Eating another organism means getting food and food is a source of energy. Not all energy of the organism being eaten is transferred to next level. Just 10% of it is transferred.
