How does the birth rate compare to the death rate of a population whose size remains constant?
The difference between the two is 'population growth' if it is a positive number or 'population decline' if it is negative.
If a population of bacteria is in steady state does that mean no bacteria are dying?
No, steady state in a bacterial population means that the birth rate equals the death rate, resulting in a stable population size. Bacteria are still dying in a steady state, but the rate of death is balanced by the rate of reproduction.
At what point on the graph is the population of horses at carrying capacity?
The population of horses reaches carrying capacity on the graph at the horizontal asymptote, where the population levels off and no longer increases despite changes in environmental factors. This point indicates that the population has stabilized and is supported by the available resources in the habitat. At this stage, the birth rate and death rate balance out, resulting in a constant population size.
What is an example of replacement rate?
The replacement rate typically refers to the birth rate at which a population exactly replaces itself from one generation to the next, without migration. For most countries, this rate is about 2.1 children per woman, accounting for infant mortality and other factors. For instance, if a country has a fertility rate of 2.1, it is considered to be at the replacement level, ensuring a stable population size over time.
What must be true for a population to remain constant over time?
For a population to remain constant over time, the birth rate must equal the death rate, ensuring that the number of individuals being born is equal to the number of individuals dying. Additionally, there should be no migration in or out of the population, as this can also impact population size.
How birth rate and death rate affect on population size?
The birth rate affects the size of population because of what its like. And the death rate is more than you can imagine.
What are the factors that affect a population's size size?
the factor are Death Rate Birth Rate Immigration
What can affect the human population size?
birth rate & death rate,fertility rate.
What will happen to population size if the birth rate is higher than the death rate?
The population size also depends on migration, for which there is no information provided.
What will happen to population size if the birth rate is higher than death rate?
The population size also depends on migration, for which there is no information provided.
What will happen to population size if the birth rate and the death rate are equal?
It doesn't change.
What happens to the population size if the birth rate is lower than the death rate?
qualitative
What are two ways that the size of population can increase?
Increased Birth Rate or decreased Death Rate
How does the birth rate change the size of a population?
More babies, more members of the population.
Is the following sentence true or false if the birth rate is greater than the death rate population size decreases?
False.. if the birthrate is greater than the Death Rate... the population INCREASES !
Does emgration effect on population size?
That depends on the balance between birth rate, death rate and emigration rate
What factors increase the size of a population?
A increase in birth rates and increase in immigration or the death rate decreases.
