The correct answer is: 90
The increase in the number of individuals in a particular time period is termed as ‘birth rate’ or ‘natality’, while the individuals dying over a time period are known as ‘mortality’ or ‘death rate’.
Birth rate = 100
Death rate = 10
Number of individuals in a population = 1000
The intrinsic rate of natural increase is = 100 – 10 = 90
