Dichotomous Key
(S7L1.a)
A dichotomous key helps us identify what exactly an organism is. The reason they are called dichotomous is because the word "dichotomous" means "divided into two parts", hence the two choices you are given when using a key. They consist of a series of choices that lead the user to the correct organism.
To develop a dichotomous key, you need at least 4 organisms. The first 2 questions should be something that all organisms have in common. Next, you branch out depending on their characteristics. Soon, you have a dichotomous key!
