Biotic Potential Organisms reproducing at their maximum rate All organisms survive to age of reproduction Succeeding generations reproduce at their maximum rate
2
Birth Rate Number of births per individual per year Example : If there are 52 births per 1,000 individuals, the per capita birth rate would be: 52/1000 or.052 births per person
3
World Birth Rates
4
Death Rate The number of deaths per individual per year Example: If there are 14 deaths per 1,000 individuals per year, the per capita death rate would be 14/1000 +.014 deaths /individual/year
5
World Death Rates
6
Growth Rate Births per capita – Deaths per capita.052 (births per capita) -.014 (deaths per capita) = 0.038 (growth per capita)
7
To Calculate New Individuals per Year Multiply the per capita growth rate by the number of individuals in the population If the population is 50,000.038 (per capita growth rate) X 50,000 = 1,900 additional individuals
