Zero growth
Equilibrium
ZPG
If the birth rate were to increase and the death rate were to remain the same, the population would grow.
The birth rate is around 12 per 1,000 population per year (world average is 20). Pretty much the same as the US. The death rate is 9-10 per 1,000 population per year. The highest in South America.
a. The birthrate becomes higher than the death rate. b. The birthrate stays the same and the death rate increases. c. The birthrate becomes lower than the death rate. d. The birthrate and the death rate remain the same.
At carrying capacity, the birth rate and death rate of the fish population will equalize. The birth rate will decrease due to competition for resources, limited space, and increased predation. The death rate will increase as resources become scarce and competition intensifies, balancing the population size at the carrying capacity of the pond.
The birth rate refers to the number of live births per 1,000 people in a given population within a specific time period. The death rate, on the other hand, is the number of deaths per 1,000 people in the population within the same time frame. These rates are commonly used to measure population growth and demographic trends.
Because the birth-rate exceeds the death-rate.
a. The birthrate becomes higher than the Death Rate. b. The birthrate stays the same and the death rate increases. c. The birthrate becomes lower than the death rate. d. The birthrate and the death rate remain the same.
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.
Zero birth rate occurs when babies are born as fast as other people in the same country are dying. Births = deaths = zero birth rate.
Birth Rate: The birth rate of a society refers to the number of births per 1,000 people in that society. This figure is expressed as the crude birth rate (CBR) and is calculated without consideration of the sex or age of the population. Death Rate: The death rate of a society is figured in the same manner but with regard to deaths rather than births and is expressed as the crude death rate (CDR). Fertility Rate: The fertility rate of a society is the average number of children which would be born by a woman during her "childbearing" years. Replacement fertility is the fertility level at which women on the average are birthing just enough children to "replace" themselves and their partners in the population.
