Answer:
40 squirrels are being added to the population per annum
Explanation:
The death rate is 0.02 per capita per annum, and the birth rate is 0.06. If the population size is 1000, the number of deaths per annum = 1000* 0.02 = 20. The number of births per annum = 1000* 0.06 = 60. Thus, total 40 numbers of squirrels are being added to the population per annum.
