During one year, eight turtles are born into a population. ten turtles immigrate into the population, but two emigrate to find mates. if the overall population growth is nine turtles, what was the death rate of turtles during the year? use this formula: population growth = (birth rate + immigration) – (death rate + emigration) a)7 b)9 c)11 d)29

A)7

Explanation:

Birth rate = 8 turtles / year

Immigration = 10 turtles / year

Emigration = 2 turtles

Population growth = 9 turtles.

Lets suppose that the death rate for the given population is X.

By placing all the values in formula:

population growth = (birth rate + immigration) – (death rate + emigration)

9 = (8 +  10) - (X + 2)

9= 18 -( X+ 2)

or X= 7.
