Given:
Birth rate of Giraffes = 28
Death rate of Giraffes = 39
To find:
Population growth rate of Giraffe population
Formula to be used:
Population growth rate = Birth rate – Death rate
Calculation:
Population growth rate = Birth rate – Death rate
Population growth rate = 28-39
Population growth rate = 11
Percentage of growth rate

Solution:
From the above calculation it can be inferred that the growth rate of the giraffe population is 0.11%.
