If a population of mice doubles every year starting with two in the first year the population would be four in the second year 16 in the third year 256 in the fourth year and would keep rising.
That is it is increasing at a greater and greater rate.
That is it is increasing at a greater and greater rate. If population number is plotted against time on a graph a characteristic J-shaped curve results see graph. The size of the population depends on the rate of birth and the rate of death. That is it is increasing at a greater and greater rate.
