1.Using Table 1‚ which of the three trials produced the highest carrying capacity for both the whales and the seals? Why do you think this trial had the best outcome for the whale and seal populations? 2.Using Table 2 and 3‚ explain how the birth rates of the seals and the death rates of the whales affected the carrying capacity for both whales and seals. 3.For the second trial in Part 1‚ we doubled the whale population and reduced the seal population by half. However‚ the carrying capacity for
