Answer:
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.
