Quizplus · Accepted Answer

A dichotomous key is a tool biologists use to identify organisms by asking a series of "either-or" questions that lead to the identification of a specific organism. The key consists of a series of paired statements or descriptions in which only one of two alternatives applies to any particular organism. By answering a series of these questions it is possible to identify the organism being studied. A species key and a binary chart are not specific tools used in biology, while an evolutionary tree is more of a visual representation of the history of species rather than a tool for identification.
