"Population ecology deals with the study of the structure and subtleties of a population which comprises of a group of interacting organisms of the same specie that occupies a given area and can be characterized as local which is a group of less number of individuals occupying a small area or met which is a group of local populations linked by disbanding members. The demographic structure of a population is a key factor which is characterized by the number of individual members present at each developmental stage of their cycle to identify whether the population of a specific specie is growing, shrinking or remain constant in terms of its size. Population structure determines the arrays of demographic variation such as mode of reproduction, age, reproduction frequency, offspring counts, gender ratio of newborns within/among populations."
