Question

Thanks to a new conservation program, a population with only 200 individuals at the beginning of the year is growing exponentially. the population has a per capita birth rate of 0.5 per year and a death rate of 0.2 per year. what is the growth rate during the year? what will the population be at the end of the year?

Answer 1

Given:
population 200 individuals at the beginning of the year
population per capita birth rate 0.5 per year
death rate 0.2 per year

200 x 0.50 = 100 birth per year
200 x 0.20 = 40 death per year

growth rate during the year: 100 - 40 = 60
population at the end of the year: 200 + 60 = 260
