The beaver population's growth rate for the current year is -13.33%.
Data and Calculations:
Past population of beaver = 15,000
Births this year = 1,000
Deaths in the year = 3,000
Decrease = 2,000 (1,000 - 3,000)
Present population of beaver = 13,000 (15,000 + 1,000 - 3,000)
Growth rate equation = (Present Population/Past Population)^1/n - 1
= (Present Population - Past Population)/Past Population x 100
= (13,000 - 15,000)/15,000 x 100
= -2,000/15,000 x 100
= -13.33%
Thus, the beaver population's growth rate for the year is negative, showing a decrease of 13.33% or 2,000 persons.
