(i) The size of the population depends on its state in the habitat. The impact of a predator or the effect of a pesticide application can be determined by evaluating the size of the population.

(ii) The age structure of a population is the percentage of individuals of different ages such as young, adult and old. The ratio of various age groups in a population determines the current reproductive status of the population. The age groups are classified as pre-reproductive, reproductive and post-reproductive.
