Quiz 15: Population, Urbanization, and the Environment

Population: Population is the total of all the organisms in a similar category. Population considers all the elements in a particular area. In a particular time gap, the population will be monitored. The opportunities will be evaluated based on the population study of a particular area. Statement: Sociology is the study regarding the social interaction of a person at every level of life. Sociology clearly explains about the behavior of a person towards the society. The statistical study about the human population is known as demography. Ecology deals with the scientific study and analysis of various organisms and its interaction with the environment. Zero population growth is an indication of no improvement or decline in the population. Hence, options (a), (c), and (d) are incorrect. Justification: Demography helps to study the human population. It is a scientific study about the human population. Hence, the option is correct.

Population: Population is the total of all the organisms in a similar category. Population considers all the elements in a particular area. In a particular time gap, the population will be monitored. The opportunities will be evaluated based on the population study of a particular area. Statement: Fertility measures the productiveness. It is necessary to consider fertility for studying the population. Fertility helps to evaluate the number of babies born in an area for a particular period. The crude birth rate is the widely used measure of fertility. Mortality is the opposite concept of fertility. Mortality studies the number of deaths in a particular locality for a specified period. The crude death rate measures the mortality in a particular area. Hence, options (a), (b), and (c) are incorrect. Justification: Mortality measures the death trend in a particular area for a particular period. The crude death rate is the widely used measure for measuring mortality. Birth crude rate is the measure used to measure the fertility. Hence, the option is correct.

Population: Population is the total of all the organisms in a similar category. Population considers all the elements in a particular area. In a particular time gap, the population will be monitored. The opportunities will be evaluated based on the population study of a particular area. Statement: Demographic transition theory is the idea to keep the population rate in line with the technological and economic development. There are four phases or stages identified by the demographic transition theory. They are as follows: • Preindustrial society • Early industrial society • Advanced industrial society • Postindustrial society Hence, options (a), (b), and (c) are incorrect. Justification: Preindustrial society, early industrial society, advanced industrial society, and postindustrial society are the phases of demographic transition theory. Declining industrial society is not the stage in the demographic transition theory. Hence, option is correct.
