Lesson 25: Classifying Using Keys
Dichotomous Key = uses pairs of statements/questions
Steps for using a dichotomous key:
1. Observe organism.
2. Select one option from a set of two descriptive statements.
3. Go to the next set of statements as directed depending on
your answer to the previous set.
4. Continue in this manner until you reach the identification
name of the organism.
