We have a scenario about mice populations living on an island surrounded by a lake, and the island has basically increased in size because the lake has dried up.
00:12
So we know the population of mice started at a thousand, and in the next three years with that population having more area to expand, it doubled.
00:24
So in year one, you would have two thousand.
00:30
By you have four thousand mice.
00:33
By year three, you have eight thousand mice.
00:36
And then year four on, we know the hawk populations have increased as well, so the birth rate and death rate are going to be equal.
00:45
So that's reflected in this line known as carrying capacity.
00:48
The deaths are equal to the births.
00:51
So we have to answer the question of the following statements about the populations of mice, which is true.
00:58
So the first statement is that the current mouse population is less than carrying capacity.
01:04
Well, we can see by this curve that it eventually flattens out when the hawk population acts as resistance to unfettered population growth.
01:14
So this flat line here reflects carrying capacity...
