To determine the population growth rate, follow these steps:
1. Determine the birth rate:
- The birth rate is calculated by taking the number of new individuals born and dividing it by the initial population.
- Birth rate = (Number of births) / (Initial population)
- Birth rate = 100 / 1000
- Birth rate = 0.10
2. Determine the death rate:
- The death rate is calculated by taking the number of individuals who died and dividing it by the initial population.
- Death rate = (Number of deaths) / (Initial population)
- Death rate = 200 / 1000
- Death rate = 0.20
3. Calculate the population growth rate:
- The population growth rate is determined by subtracting the death rate from the birth rate.
- Population growth rate = Birth rate - Death rate
- Population growth rate = 0.10 - 0.20
- Population growth rate = -0.10
Therefore, the correct equation to show how to calculate the population growth rate of this population is:
