If the penguin population fluctuates around the car - rying capacity, what was the approximate carrying capacity of the island for the penguin population from 1960 to 1975

This is an incomplete question. The graph is missing.

The answer is 5700 penguins.

Explanation:

In an environment, the carry capacity of any species is the maximum population size or density that habitat or an environment can sustain the species indefinitely, provided that food, water, habitat are available in the habitat.

Earlier most of Emperor penguin density is in the J-shaped phase of the curve, but later on the number fluctuates on carrying capacity and they entered into the S-shaped curve. Thus there was 5700 penguins according to the graph from 1960 to 1975.
