Types of Dichotomous Key:
- Nested Style. This is when the next identification question appears nested under the answer leading up to it.
- Linked Dichonotomous Key: In this kind, questions are written in a listed form, each answer leads to a different question on a different line.

What is the difference between dichotomous keys and flow charts?
In this manner, dichotomous keys are similar to flow charts; both require an input of information that directs where the key/chart will go next. Flow charts are directed by previous inputs of information, much like dichotomous keys.
