How can one determine the natural increase rate of a population?

To determine the natural increase rate of a population, you can subtract the death rate from the birth rate. This calculation gives you the rate at which the population is growing or declining without considering factors like migration.


What must occur for a population to grow?

For a population to grow, the birth rate must exceed the death rate, there must be enough resources available to support the increase in population, and factors that limit growth such as disease or predation must be controlled.


When is it possible for a population growth rate to be less than zero?

Zero population growthThe so-called replacement rate is about 2.2 births per fertile woman. That's what a society needs to maintain zero population growth. That "extra" 0.2 people is what's needed to account for premature deaths -- deaths that occur before procreation. Zero population occurs when the numbers of birth rate and death rate are the same/equal.


What are three things that can change a population?

The biggest thing that can change a population is the availability of jobs in that are. 2 other things that can change the population of an area is what businesses are there and the crime rate.


Imagine a disease that killed 50 percent of the male roachs in population Do you think this will affect birth rate?

Yes, a disease that kills 50% of the male roach population would likely decrease the birth rate for roaches, as there would be fewer males available to mate with females. This imbalance could result in a decline in the number of offspring being produced.
