conclusion:
be sure to answer the following reflection questions in the conclusion of your lab report:
· were your hypotheses correct or incorrect? why or why not?
· 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:
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?
what are the limitations of the population dynamics lab? is the lab activity a realistic representation of an arctic marine
ecosystem? note: provide detailed support for your opinion.
