  1. One advantage of dichotomous keys is that because you need to know about the organism that you are trying to identify, you learn a lot about the words that are needed to be known (like calyx, corolla, and whorls) and the abbreviations (like fls and lvs) that the identifier needs to know and learn in order to follow and use the key.
  2. Another advantage is that can be split up into separate areas or sections, for example having a key for grasses, another for wildflowers, another for birds, land mammals, aquatic mammals (whales and dolphins) etc.
  3. One last advantage of dichotomous keys is that with this type of key you are able to compare the characteristics of various similar species.
