No links please, and thank you in advance :) Can someone give me an example of a dichotomous key, I have learned a little about it.. but I’m still a little confused. Can I have an example?

important scientific tool used to identify different organisms, based the organism's observable traits

Explanation:

consist of a series of statements with two choices in each step that will lead users to the correct identification

For example, in tree identification, a dichotomous key might ask whether the tree has leaves or needles. The key then directs the user down one list of questions if the tree has leaves, and a different question list if it has needles.

Example objects to identify: apple tree, water-lily, fir tree, dandelion, astroturf, seaweed. Dichotomous keys may be simple or complex depending on what is being identified. I hope this helps
