Question

When the birth rate is equal to each woman producing exactly enough offspring to replace herself and her offspring's father, and the birth rate is sustained for a generation, then ________.

Answer 1

Then the net population growth is zero.

Explanation:

When the birth rate is equal to each woman producing exactly enough offspring to replace herself and her offspring's father, and the birth rate is sustained for a generation, then there will be no increase in population so the net population growth will be zero.

Population of species is defined as the number of individuals of a given species.

For example, if their were 50 individuals in a population and a woman out of them mates with a man and produces one offspring to replace her and one offspring to replace her offspring's father, and then both of them die.

So the intrinsic rate of population growth = No. of birth -no. of death

                                                                     $=2-2$

                                                                     $= 0$

                                  Growth rate $= \frac{dN}{dN} = rN$

                                                        $=0$
