Title:Lab Report for Population Dynamics Lab Objective(s):
Research: Prey Initial Size, Prey growth rate, predator entail size, predator death rate, Capture efficiency.
List the variable descriptors for the lab here.
Hypotheses: If the death rate of the whales increases, the resulting population of seals will be higher than the population of whales for sure. (both starting at population at 25)

Analysis and Conclusion:
Be sure to answer the following reflection questions as a summary paragraph in the conclusion of your lab report:
Were your hypothesis correct or incorrect? Why or why not?
Which factors affecting population growth and decline are modeled with the graphs?
Using Table 1, which of the three trials produced the highest population for both the whales and the seals? Why do you think this trial had the best outcome for the whale and seal populations?
Using Table 2 and 3, explain how the birth rates of the seals and the death rates of the whales affected the population for both whales and seals.
Questions:
Using what you have learned from the lesson and the virtual lab activity, answer the following questions in complete sentences:
Describe three additional biotic and abiotic factors not modeled in the simulation that could affect the population dynamic of the whales and seals.
Explain why some limiting factors may lead to drastic changes in whale and seal populations, while others may only cause minimal changes.
In this lesson, you learned about two patterns of population growth and decline, the sigmoid and peak phenomena. Does the seal and killer whale relationship represent a sigmoid or peak phenomenon? Please provide supporting details.
