how many choices are given at each step in a dichotomous key.
Question
how many choices are given at each step in a dichotomous key.
Solution
In a dichotomous key, two choices are given at each step. The word "dichotomous" is derived from the Greek word "dichotomia" which means "divided in two parts". Therefore, at each step in a dichotomous key, you have to choose between two options to proceed to the next step. This process continues until you have identified the specific item or organism you are trying to classify.
