Detailed explanation-1: -Population rely on density Density is the number of individuals per unit area or volume. Counting the number of organisms inhabiting a certain area is often very difficult, if not impossible. Dispersion is the pattern of spacing of individuals within the area the population inhabits.

Detailed explanation-2: -The dispersion pattern (distribution pattern) of a population describes the arrangement of individuals within a habitat at a particular point in time, and broad categories of patterns are used to describe them. The three dispersion patterns are clumped, random, and uniform (figure 5.1. a).

Detailed explanation-3: -Summary. Population size is the number of individuals in a population. Population density is the average number of individuals per unit of area or volume. The pattern of spacing of individuals in a population may be affected by the characteristics of a species or its environment.

Detailed explanation-4: -Dispersion patterns are the spatial pattern of individuals within a population after the individuals have dispersed. There are three types of population dispersion patterns: uniform, random, and clumped.
