Population Density

Which is the correct formula in calculating population density?

• D = population/area

• D = population x area

• D = number of runs/total population

• D = number of runs x total population

Which situation illustrates the relationship between a limiting factor and population density?

• When birth rate is greater than death rate, population increases.

• When the population in a given area increases, the population density also increases.

• Population sizes change with the number of births or when organisms move out of an ecosystem.

• When the population of goats and cows in a field increases rapidly, there may not be enough food for each of them.

The average number of people living in a square kilometre.

• population density

• population distribution

• densely populated

• sparsely populated

Overpopulated

• population density is below the carrying capacity of the environment

• population density is equal with the carrying capacity of the environment

• population density is exceeding the carrying capacity of the environment

• population density is twice less the carrying capacity of the environment
