In a population of ants, the per capita birth and death rates are 0.04...
The birth rate is more than the death rate so the population will increase by the rate 0.04–0.02 = 0.02.
The number of ants added will be 0.02×1000 = 20
The number of ants added will be 0.02×1000 = 20

In a population of ants, the per capita birth and death rates are 0.04...
Per Capita Birth Rate:
- The per capita birth rate is given as 0.04, which means that on average each ant in the population gives birth to 0.04 new ants in one year.
Per Capita Death Rate:
- The per capita death rate is given as 0.02, which means that on average each ant in the population dies at a rate of 0.02 ants per year.
Population Size:
- The initial population size is given as 1000 ants.
Calculating the Number of Ants Added or Lost:
To calculate the number of ants added or lost from the population at the end of one year, we need to subtract the number of ants that die from the number of ants that are born.
Number of Ants Born:
- The number of ants born can be calculated by multiplying the per capita birth rate by the initial population size.
- Number of ants born = Per capita birth rate * Initial population size = 0.04 * 1000 = 40 ants.
Number of Ants Died:
- The number of ants that die can be calculated by multiplying the per capita death rate by the initial population size.
- Number of ants died = Per capita death rate * Initial population size = 0.02 * 1000 = 20 ants.
Net Change in Population:
- The net change in population is calculated by subtracting the number of ants that die from the number of ants that are born.
- Net change in population = Number of ants born - Number of ants died = 40 - 20 = 20 ants.
Conclusion:
- At the end of one year, the population of ants will have a net increase of 20 ants.
- This means that 20 ants will be added to the population, resulting in a total population of 1020 ants.
- The per capita birth rate is given as 0.04, which means that on average each ant in the population gives birth to 0.04 new ants in one year.
Per Capita Death Rate:
- The per capita death rate is given as 0.02, which means that on average each ant in the population dies at a rate of 0.02 ants per year.
Population Size:
- The initial population size is given as 1000 ants.
Calculating the Number of Ants Added or Lost:
To calculate the number of ants added or lost from the population at the end of one year, we need to subtract the number of ants that die from the number of ants that are born.
Number of Ants Born:
- The number of ants born can be calculated by multiplying the per capita birth rate by the initial population size.
- Number of ants born = Per capita birth rate * Initial population size = 0.04 * 1000 = 40 ants.
Number of Ants Died:
- The number of ants that die can be calculated by multiplying the per capita death rate by the initial population size.
- Number of ants died = Per capita death rate * Initial population size = 0.02 * 1000 = 20 ants.
Net Change in Population:
- The net change in population is calculated by subtracting the number of ants that die from the number of ants that are born.
- Net change in population = Number of ants born - Number of ants died = 40 - 20 = 20 ants.
Conclusion:
- At the end of one year, the population of ants will have a net increase of 20 ants.
- This means that 20 ants will be added to the population, resulting in a total population of 1020 ants.
