Detailed explanation-1: -Populations are individuals of a species that live in a particular habitat. Ecologists measure characteristics of populations: size, density, dispersion pattern, age structure, and sex ratio. Life tables are useful to calculate life expectancies of individual population members.
Detailed explanation-2: -Ecologists estimate the size and density of populations using quadrats and the mark-recapture method. The organisms in a population may be distributed in a uniform, random, or clumped pattern.
Detailed explanation-3: -The dispersion of a population is the pattern of spacing among individuals within the geographic boundaries.
Detailed explanation-4: -Population density is the number of individuals per unit geographic area, for example, number per square meter, per hectare, or per square kilometer.
