In a logistic model, what happens if a population exceeds carrying capacity? it goes back to exponential growth.
00:08
The size of the population remains constant.
00:11
It begins to decline, or the population goes extinct.
00:15
So a logistic model, it looks like this.
00:20
So it has an exponential phase, but it slows down as it approaches carrying capacity, and then it stays at carrying capacity, which will have its k.
00:29
So what would happen if, hypothetically, it overshot? would it resume exponential growth? no, definitely not.
00:39
Would it remain constant at its new peak, like so? again, no, it wouldn't.
00:47
Would it go extinct? or would it simply decline? well, the point of carrying capacity is that carrying capacity is the maximum sustainable population.
01:01
So there's some kind of limit here.
01:04
Perhaps it's resources, perhaps it's space, but it's the maximum sustainable population.
01:11
It doesn't mean that it can never go above carrying capacity.
01:14
It just means it will not stay there for long...
