If the current population size of bison is 3,652 and the maximum growth rate of the population is 0.28, calculate the population

s344n2d4d5 [400]

Given:

Present population of bison = 3652

Maximum growth rate = 0.28

To find:

The population of bison after one year.

Solution:

The future population can be calculated with the help of the following formula,

$P_F=P_P\times(1+r)^n$

where $P_F$ is the future population, $P_P$ is the present population, r is the growth rate and n is the number of years.

On substituting the given values in the formula we get,

$\Rightarrow P_F=3652\times(1+0.28)^1$

$\Rightarrow P_F=3652\times1.28\rightarrow4674.56\approx4675$

Therefore, the population size of bison after one year is 4675. The park does not have to control the population because the growth rate is on an average scale.
