Question

Which of the following is not a factor that would limit the growth of a population?
(A) Food shortage
(B) Immigration
(C) Disease
(D) Famine

Answer 1

Hint: The situation in which the population of a country keeps on expanding due to decrease in mortality that is death rate and increase in fertility that is reproduction rate, also called as natality it is said that the demographic dividend of the country is increasing. The growth increases when resources become unlimited, that is they are available for unlimited use and there is no competition between organisms.

Complete answer:
Human population is the top research study and it is a fascinating field of study. You must be thinking and observing what truly is studied in the human population? So the answer is the human population of a region or a country shows the socio-economic aspect. It tell with which speed and how fast the population is growing, it gives information about the factors that are responsible for growth, it shows that some countries have a high and enlarging rate of population growth when taken comparison to others, what is the ratio of females to males in a particular region, etc. are some of the composition of human population study.
Now let us see the details of this option:
> Food shortage :- Maximum number of individuals of a population which can be supported with optimum resources for their survival is called carrying capacity. When resources are limited competition is maximum. So population growth is limited
> Immigration :- It is the number of individuals of the same species that have come into the habitat from some different place during the time period that is taken under observation. This may help to increase and enlarge the growth or prevent extinction of a smaller population. In plants, it is equivalent to disseminules.
> Disease :- When the functioning of one or more organs or systems of the body is adversely affected, characterized by various signs and symptoms, we say, that we are not healthy, i.e., we have a disease. it limits the growth.
> Famine:- when due to any natural calamity such as drought , flood or any other condition and shortage of food occur resources get limited. When resources are limited competition is maximum. So population growth is limited

Our required option is B that is Immigration.

Note:
There is a branch of science that deals with the studying of the human population and this branch is called demography. When there is an increase in population occurs, for instance there is a large number of individuals in working age groups (in the case of India, it is 15-64 years), or large number of people in reproductive age, it is said that the country is rich in demographic dividend.
