When using a dichotomous key, you always start with number 1. This first step typically presents a question or characteristic that helps you narrow down your options. Based on your observation, you follow the corresponding path, leading you to the next number until you arrive at the identification of the organism or item in question.
To sort 10 organisms using a dichotomous key, you need a minimum of 9 couplets. Each couplet provides a choice that effectively reduces the number of organisms by half until only one organism remains. Thus, with each couplet, the number of remaining options decreases, and for 10 organisms, 9 couplets are needed to reach the final identification.
To identify a species using a dichotomous key, start at the first couplet, which presents two contrasting statements about characteristics of the organism. Choose the statement that best describes your specimen and follow the corresponding direction to the next couplet. Continue this process, answering the questions until you reach a final identification of the species. This systematic approach allows for the identification of various organisms based on observable traits.
One disadvantage of using dichotomous keys is that they can sometimes be complex and difficult to navigate, especially for individuals who are less familiar with the terminology or characteristics being used in the key. Additionally, mistakes or errors in identification can occur if the key is not carefully followed or if the characteristics are ambiguous.
Dichotomous questions are easy to understand and answer quickly, making them ideal for surveys or questionnaires with limited response options. They can also provide clear-cut data analysis, making it easier to draw conclusions and compare responses.

There are various things that could go wrong when using a dichotomous key. For instance missing essential information would affect the dichotomous key entirely.
