Question

In a population of deer, the birth rate is 5, the death rate is 4, immigration is 8, and emigration is 6. Calculate the population growth by filling in the formula of population growth.r = (b+i)-(d+e)Population growth (r)Birth rate (b)Death rate (d)Immigration rate (i)Emigration rate (e)

Answer 1

We have the following data:

Birth rate (b) = 5

Death rate (d) = 4

Imigration rate (i) = 8

Emigration rate (e) = 6

The formula for population growth (r) is:

r = (b+i) - (d+e)

So we have the following:

r = (5+8) - (4+6)

r = 13 - 10

r = 3

The population growth is then measured in 3.
