because every 3 seconds someone is born. every 5 seconds someone dies
At carrying capacity, the population size stabilizes as the birth rate equals the death rate, resulting in no net increase in the number of organisms. This balance occurs when resources such as food, water, and habitat are limited, preventing further population growth. Consequently, the ecosystem can sustain the population without degradation, maintaining a stable environment.
At carrying capacity, the number of organisms being born equals the number of organisms dying. This balance means that the population size remains stable over time, as the birth rate matches the death rate. Environmental resources are fully utilized, and any increase in population would lead to competition for those resources, potentially decreasing the population again.
At carrying capacity, the population size stabilizes as the birth rate equals the death rate, resulting in no net increase or decrease in the number of organisms. This equilibrium occurs when the environment's resources, such as food, water, and space, can adequately support the population. Consequently, the ecosystem maintains a balance, ensuring that the number of individuals remains relatively constant over time.
Population stabilization: Common term for zero population growth, in which the birth rate equals the death rate and in addition where net immigration equals net emigration so that the population does not increase or decrease over time. Usually used in the context of stabilizing increasing populations.http://www.susps.org/overview/population_terms.html
the birth rate is the rate of birth in a population, the death rate is the number of deaths in a population and the growth rate is the growing numbers of the population.
The formula for calculating birth rate is (Number of Births / Total Population) x 1000. This formula allows you to determine the number of births per 1,000 individuals in a given population over a specific period of time.
The number of births in a population over a certain amount of time is known as the birth rate. It is usually expressed as the number of live births per 1,000 individuals in a population per year.
birth rate and death rate.
Birth Rate
South Dakota's Birth Rate for 2008, based on number of births per 1,000 population is 15.0.
The birth rate is calculated by dividing the number of live births in a year by the total population, then multiplying by 1,000 to express it as a rate per 1,000 people. The formula is: (Number of live births in a year / Total population) x 1,000.
