Answer:
Option A, increases by 40 individuals
Explanation:
Given,
Annual per capita birth rate [tex]= 0.055[/tex]
Annual per capita death rate [tex]= 0.015[/tex]
Net per capita population growth rate
[tex]= 0.055 - 0.015\\= 0.040[/tex]
The growth equation of population
[tex]\frac{dN}{dt} = r^N[/tex] Eq 1
On simplifying we get
[tex]N = N_0 * e^{-rt}\\[/tex]
Substituting the given values in Eq 1, we get -
[tex]\frac{dN}{dt} = 0.04 * 1000\\\frac{dN}{dt} = 40[/tex]
Hence, the population increase by [tex]40[/tex] individuals.
Option A is correct
