What happens to population when the death rate is very close to the birth rate?
It achieves what used to be called "ZPG" - zero population growth. Births and deaths are essentially equal. The population sustains itself where it is, but does not grow or shrink.
How is population size in an ecosystem determined by the relative rates of birth immigration emigration and death?
Birth and immigration both add individuals to a population, increasing the population size. Similarly, deaths and emigration remove individuals, reducing the population. So growth would be equal to the sum of immigration and births, minus the sum of emigration and deaths.
What does it mean if a population is in equilibrium?
The birth rate and the Death rate are equal, providing there is no immigration/emigration of the population.
When something is neither growing nor shrinking.?
When something is neither growing nor shrinking, it is said to be in a state of equilibrium or stasis. This condition implies that the forces acting on it are balanced, resulting in a stable state where there is no net change over time. For example, in ecology, a population at carrying capacity experiences this balance, where birth and death rates are equal. Similarly, in economics, a market at equilibrium has supply equal to demand, leading to stable prices.
What happens when inductance is equal capacitance?
Inductance and capacitance are never equal, since they have different units.It's like asking "What happens when temperature is equal to cost ?"It's possible for the inductive and capacitive reactances to be numerically equal,though. That only happens at one frequency, and when it does, your circuit isat resonance.
What happens as the population decreases?
As a population decreases the death rate is higher or equal to the birthrate.
What happens to population when the death rate is very close to the birth rate?
It achieves what used to be called "ZPG" - zero population growth. Births and deaths are essentially equal. The population sustains itself where it is, but does not grow or shrink.
When does a population not change?
When the death toll and birth rate of people are equal around the world.
What will happen to population size if the birth rate and the death rate are equal?
It doesn't change.
What is the stationarity population in population study?
In demographics stationary population is when the death rate and birth rate are equal therefore the population is neither decreasing or increasing but it is stationary.
What is the model of population growth that states the growth rate remains constant because birth and death rates are equal?
The model of population growth that states the growth rate remains constant because birth and death rates are equal is called zero population growth or ZPG. In this scenario, the population size does not increase or decrease over time due to the balance between births and deaths.
What are the three types of population pyramids?
Expansive population pyramid: wide base and narrow top, indicating high birth and death rates. Constrictive population pyramid: narrow base and wider top, showing low birth and death rates. Stationary population pyramid: nearly equal widths at all age groups, suggesting stable birth and death rates.
Comparison between crude birth rate and death birth rate?
simple thing.. no of death is equal to 4 times larger than the no of birth....
How is population size in an ecosystem determined by the relative rates of birth immigration emigration and death?
Birth and immigration both add individuals to a population, increasing the population size. Similarly, deaths and emigration remove individuals, reducing the population. So growth would be equal to the sum of immigration and births, minus the sum of emigration and deaths.
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.
What does it mean if a population is in equilibrium?
The birth rate and the Death rate are equal, providing there is no immigration/emigration of the population.
Zero population growth can be achieved when?
When the death rate and the birth rate are equal. This basically means that the amount of people that are dying are being replaced by babies being born. But no extra babies are being born so there is no population growth.
