a population of 1500 individuals is experiencing exponential growth
if 135 births and 45 deaths occur in one year the intrinsic rate of
natural increase of that population is ?

Dear student,
We know that there are 135 births in the population over the
month, in our population of 1500 individuals; we can express this
as a rate by doing the following:
Birth rate = 135/1500 = 0 09 births/(indiv x year)
Using the same logic…
Death rate = 45/1500 = 0 03 deaths/(indiv x year)
instrinsic rate of increase (r) = birth rate - death rate = 0 09
- 0 03 = 0 06
