Question

NEED HELP!! I have to do a lab report for Population Dynamics Lab. I am horrible at this. Here are the questions:

Analysis and Conclusion:

Be sure to answer the following reflection questions in the conclusion of your lab report:

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.
Climate change (an abiotic factor) has slowly decreased habitat for the arctic seals. Predict how a reduction in habitat could change the capture efficiency of the killer whales. How would this affect the carrying capacities for both the whales and the seals?
If another source of prey were available to the whales, what changes in population size would you expect for the seals and the whales?
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.
What are the limitations of the population dynamics lab? Is the lab activity a realistic representation of an arctic marine ecosystem? Note: Please provide detailed support for your opinion.

Answer 4

that's the whole thing
