Ecology Online Simulation

Measuring species interactions and resulting population changes can be challenging. It often requires intensive field work over several seasons and locations, extensive funding, and numerous skilled scientists. Simulations allow us to learn about species interactions and population dynamics through play and exploration. This ecological simulation is an opportunity to experiment with species interactions in order to learn about different potential outcomes. Responses to follow-up questions should be based on the simulation results and content from your textbook, as well as other scholarly or credible sources.  To complete the ecology laboratory assignment for this week, follow the steps below: •Read this week’s assigned chapters •Download and review the Ecology Laboratory Instructions (Links to an external site.)Links to an external site. and follow the steps indicated. •Download the Ecology Laboratory Reporting Form (Links to an external site.)Links to an external site.. All of the data will be reported and the questions answered directly on this form. This is the form that you will submit to Waypoint for grading.  When completed, save the Ecology Laboratory Reporting Form (Links to an external site.)Links to an external site. as a Word document. No title page or headers are necessary. If you include any outside resources to complete the questions, then they should be formatted according to APA

*The first answers have been completed for you to help ensure that you are on track.

 

1. Which plant (also called producers) dominates over the other? Provide reasons that explain why one plant can be dominant over another?

2. Explain how herbivory might affect a plant. Your answer should consider lethal effects (i.e. mortality) and nonlethal effects such as impacts to plant size, number of seeds produced, and ability to photosynthesize.

 

3. Explain how adding the herbivore can alter the competition between plants A and B?

 

Table 3: Population prediction for food chain

 

Table 3	Plant A	Plant B	Herbivore A (eats plant A)	Omnivore A (eats Herbivore A)	Top Predator (eats Omnivore A)
Prediction (increase, decrease or die out)
Simulation Result (increase, decrease or die out)

 

*You will not lose any points if your predictions are incorrect. Just explain why in the answer below.

 

4. Was your prediction correct? How did you arrive at your prediction? What differences were there between your prediction and the simulation?

 

1. 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?

Prediction (increase, decrease or die out)
Simulation Result (increase, decrease or die out)

 

*It is ok if you predictions are incorrect. You will not lose any points. Just explain the why in the answer below.

 

6. Was your prediction correct? How did you arrive at your prediction? What differences were there between your prediction and the simulation?

 

1. Which species die out? Explain why this might happen.
