A population of cheetahs has a birth rate of 5 and a death rate of 15. Immigration is 2, and emigration is 4. What is its population growth?

0 -12
O 12
O 14

-14

Explanation:

The population growth is defined as an increase in the number of individuals in a population. The growth of a population depends largely on the birth and death rates as well as migration in and out of the population. Mathematically, the population growth can be expressed as:

(B-D) + (I - E), where B = birth rate, D = death rate, I = immigration, and E = emigration.

In the illustration, B = 5, D = 15, I = 2, and E = 4. Therefore;

Population growth = (5 - 15) + (2 - 4) = (-10) + (-4) = -14

Hence, the population growth is -14.
