• 1

• 2

• 3

We know that population sizes change over time. All statement(s) are true about this change EXCEPT:

• When there are more births than deaths the population size will increase.

• When there are more deaths than births the population size will decrease.

• When there are more deaths than births the population size will increase.

• When there are more births than deaths the population size will increase
