Answer 2

Answer:

The formula for determining population growth rate is

$G r=\frac{N}{t}$

Explanation:

Here, Gr = 'Growth rate' expressed as a 'number of individuals'.  

N = 'total change in population size' for the 'complete time period', also expressed as a 'number of individuals.'  

t =time, usually it is expressed in number of years.  

To calculate the total growth rate, we have to find out the first N. This N is calculated by 'subtracting' the 'initial population' (P1) from the 'current population' (P2).

N=P2-P1
