Question

A population of scarab beetles has an annual per capita birth rate of 0.8 and an annual per capita death rate of 0.5. Estimate the number of individuals added to or lost from a population of 1,000 individuals in one year. Please choose the correct answer from the following choices, and then select the submit answer button. 3,000 individuals added 50 individuals lost 300 individuals added 30 individuals added 500 individuals lost

Answer 1

Option C

Step-by-step explanation:

Given the annual per capita birth rate is
`0.8`

Annual per capita death rate is
`0.8`

Net per capita growth or reduction in the population will be equal to the difference between the birth rate and death rate.

Hence, net per capita increase in the population is equal to

`0.8 -0.5\\=0.3`

Thus, the total number of individuals added to the population of 1000 is equal to

`0.3 * 1000\\= 300`

Hence, option C is correct
