Bunny Population Line Graph:
(Go to
Insert,
Chart, Line, and then click okay. From there you can design the line chart as you like. Your line chart should use the data you have collected that shows how poulation numbers increaed or decreased for each scenario. Remove these directions.)
To change data in your graph, double click on the graph, then click
Chart Design on the ribbon, and then click
Edit Data in Excel.
Questions:
1. When you ran the simulation without any limiting factors in the introduction, what happened?
Answer ___
a. The bunny population went through a boom-and-bust cycle.
b. The bunny population exploded, and the simulation ended.
c. The bunny population declined slowly over many generations.
d. The bunny population exhibited a logarithmic growth pattern.
2. Of the three scenarios (limited food, wolves and wolves + mutation), which seems best for growth and stability of the bunny population?
Answer ___
a. Bunny population with limited food
b. Bunny population with wolves
c. Bunny population with wolves + mutation
3. If necessary, run the simulation of the bunnies and wolves again, paying attention to the number of wolves each time. What was unrealistic about the wolf numbers? What would you expect to happen to the wolf numbers over time in a scenario like this? Answer in complete sentences.
Answer:
4. What was the effect of having a diverse color rabbit population when there was a limiting factor? What does this tell you about the importance of genetic variation? Answer in complete sentences.
