Classification systems are important because they organize items into groups based on common characteristics. This makes it easier to find and identify things. For example, music stores organize their CDs by music type and artist. Shoe stores also classify shoes into groups like boys, girls, men and women to make shopping easier. Scientists use classification to group organisms based on shared traits. A dichotomous key is a classification tool that uses yes/no questions to identify organisms by separating them into increasingly specific groups. The document provides examples of how a dichotomous key can be used to classify insects and animals into groups based on characteristics like number of legs, wings, and tails.Read less
