Population Density
A more complete description of a population's size includes the population density — the size of a population in relation to the amount of space that it Age Structure
Age structure can be represented graphically with a population pyramid (Figure 3) Fecundity
While maximum fecundity is a constant for populations, realized fecundity varies over time based on the size, density Mortality
To visualize mortality and fecundity within a population Sex Ratio
Interestingly, sex ratio is not always random but can be manipulated at birth by environmental or physiological mechanisms Demography: describing populations and how they change In many cases, ecologists aren't studying people in towns and cities. Instead, they're studying various kinds of plant, animal, fungal, and even bacterial populations. The statistical study of any population, human or otherwise, is known as demography.Scientists study a population by examining how individuals in that population interact with each other and how the population as a whole interacts with its environment.
