Population size is the number of individuals of all ages alive at a particular time in a particular place. Spe(cid:272)ies" ra(cid:374)ge is how widely a population is spread. Population density is defi(cid:374)ed as a populatio(cid:374)"s size divided (cid:271)(cid:455) ra(cid:374)ge. Population density tells us how crowded or dispersed the individuals of a population are. These three key features are important as the information gained from these helps us understand what factors will limit a population. The pattern of population distribution can tell you about how a species may be thriving in relationship to their food source.
