How to use a dichotomous key
by Maarten Labrie
A dichotomous key is a key that is used to classify a organism

Use the table below for the example. So for example if we used the tree below we might classify a human like this:
It doesn't use photosynthisis so you would follow the "NO line".
But it is multicellular so you would follow the "YES line".
A humans cells have a nucleus so you would follow the "YES line".
Humans are not protists so you would follow the "NO line".
Now at the end we've got the name of our organism "Homo Sapiens" also known as the human.

Heres the table:

Now i hope you under stand what a dichotomous key is and how it is used.

PS. this isn't how they really classify organisms
