Keys in biology are used to identify the different species based on the easily identifiable features of the organism. A dichotomous key consists of a series of questions on features like habitat, mode of nutrition, class to which they belong and other features, with each question having two answers describing the characteristic features of an organism. The series of questions begin with a broader characteristic feature becoming narrow gradually and helping in the identification of the organism.
