The correct Answer is:
To solve the question "A population with equal number of birth and death will show," we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Population Dynamics**: - In ecology, populations are characterized by their birth rates (the number of births in a given time period) and death rates (the number of deaths in the same time period). 2. **Equal Birth and Death Rates**: - When a population has an equal number of births and deaths, it means that the birth rate is equal to the death rate. 3. **Implications of Equal Rates**: - If the birth rate equals the death rate, there will be no net change in the population size. This means the population will neither grow nor shrink. 4. **Stability of the Population**: - A population in this state is considered stable. It can be described as being in a "plateau phase," where the population size remains constant over time. 5. **Conclusion**: - Therefore, the answer to the question is that a population with equal numbers of births and deaths will show a plateau phase, indicating stability in population size. ### Final Answer: A population with equal number of births and deaths will show a plateau phase. ---

Number of birth per 1000 is

Assertion: In a population birth rates refers to per capital birth and death rate refers to per capita deaths. Reason: The birth and death rates expressed in change in numbers (increase or decrease) with respect to the members of the populations.

Following data relates to density of population , number of deaths and population of various cities. Calculate death rate and Karl Pearson coefficient between density of population and death rate:

A population that exhibits birth rates that are identical to the death rate implies.

The number of births during a period in the population that are added to the initial density is called natality.

In a given population of 2000 indivials, 80 births and 125 deaths were reported over a given period of time. Which of the following graphs will correspond to it ?

Following table summarises the differences between natality and mortality. Select the incorrect ones. {:("Natality","Mortality"),((i)"Natality is number of births per unit population per unit time.","It is number of deaths per unit population per unit time."),((ii)"It adds new individuals to the population.","It removes individuals from the population"),((iii)"It increase the size of population.","It decreases the size of population"),((iv)"It increase population density.","It reduces population density."),((v)"It is low when population size is small and high when population size is large.","It is high when population size is small and low when population size is large."):}

Number of immigration is more than emigration and death is lower than natality. Growth curve of population will show
