The carrying capacity is just as the name suggests, the maximum number of individuals that can make up a population.
Why are the others wrong?
Migration might change the carrying capacity, depending on where the species go, it can increase or decrease, but it's not the only way. A - Wrong.
It can actually be for any type of species, no matter what their distribution type is. B - Wrong.
The survivorship patter doesn't actually matter, and it really doesn't have much to do with the carrying capacity. C - Wrong.
It can vary from population to population, depending on their reproduction rate and their location (amount of resources available). D - Wrong.
Why is E. right?
It's the only one that provides us with truthful information, in a way that makes sense. If enironmental conditions change, it might not affect a population directly.
Let's say, it's a dear population. If it gets too cold, the plants they feed on might die, and they will not have food, but the cold isn't affecting them directly - they will not die because of the cold itself, but because of what the cold will do to their food.
Answer:
E.

The growth pattern we see is called logistic growth - the population grows until the carrying capacity and then stabilizes.
Since they give us a chart with a logistic growth, basing oursefls on the definition above, the limit of the growth line will be the carrying capacity of the population, therefore, 2000.
Answer:
200.
