Density is a measure of population distribution and can be calculated by dividing the total population by the total land area. It is commonly expressed as the number of individuals per square mile or square kilometer.

Density Dependencea. Add density dependence to the prey population(1) This means that the prey population will regulate its own numbers.(1) The amplitude of the oscillations gets smaller over time(convergent oscillations).(2) Eventually, both Ns are constant.b. Up to now, the equations have assumed that the predator takes prey items in direct proportion to their availability.
Tropical rainforests, such as those found in the Amazon Basin and Southeast Asia, have the highest density of organisms due to the warm climate, abundant rainfall, and diverse ecosystems that support a wide variety of plant and animal life. These regions are known for their exceptional biodiversity and high number of species per unit area.
The number of individuals per unit area is called population density. It is calculated by dividing the total number of individuals in a given area by the total land area of that region. Population density is often used to assess the level of crowding or competition within a population.
An arithmetic density is a population density measured as the number of people per unit area of land.
Mass density: The amount of mass per unit volume of a substance. Population density: The number of individuals per unit area in a population. Energy density: The amount of energy stored in a given volume or mass of a substance.
Arithmetic population density is the population of a country or region expressed as an average per unit area. The figure is derived by dividing population of the areal unit by the number of square kilometers or miles that make up the unit.
population density
Pop. density is the aver population per unit area. So to find P.D. divide population by area.

Population density is determined by dividing the total population of an area by its total land area. It is typically expressed as the number of people per square mile or square kilometer. High population density indicates a crowded area with many people living closely together, while low population density suggests a more sparsely populated region.
Population Density is the number of people per square unit of arable land. So it could be expressed and persons per square (any area unit) but is most commonly displayed as persons per square mile or persons per square kilometer.
A "density" is an amount of something per unit area. Population, for example, is defined only at the sampling unit level--household, block, census tract, county, state, or other region--but is frequently reported as a density: people per square mile, per square kilometer.
a measurement of population per unit area or unit volume.
