You are studying a density - dependent turtle population that has the following relationships for the birth rate b’ and the death rate d’ as a function of population size (N) :  b’ = 0.10 + 0.03 N - 0.0005 N ^2  d’ = 0.20 + 0.01 N Plot these functions in the same graph and discuss the population dynamics of the turtle. How does this model differ from the simple logistic model with linear birth and death functions?

Question

You are studying a density - dependent turtle population that has the following relationships for the birth rate b’ and the death rate d’ as a function of population size (N) : 

b’ = 0.10 + 0.03 N - 0.0005 N ^2 

d’ = 0.20 + 0.01 N

Plot these functions in the same graph and discuss the population dynamics of the turtle. How does this model differ from the simple logistic model with linear birth and death functions?
