Question

Population in terms of number is not always a necessary parameter to measure population density. Justify with two examples.

Answer 1

if we compare population of chlamydomonas in pond which is in millions and a banyan tree which is single so here population density should not be in terms of number it should be in biomass because a single banyan tree contributes a lot to environment

Answer 2

Population can measure the number of species that live in a particular area, and the statistical report of population is called demography. You can measure the population according to their size, number of individuals and density.

You need to measure the number of individuals per unit area or volume to indentify the density. But we cannot produce accurate density report by calculating the population of particular area.

For example, you can say that the population of New York city is 9 million and if you move into the New York city then the population will be increased automatically.
