Hi, fbihansip. I didn't realize you answered my question until today. Thank you. I'm still getting used to Course Hero's Layout. 
The Dichotomus key is supposed to be in the form of a graph (sorry this wasn't made clear). Unless this was on page 2 that was blank. I will upload example. This is a great start though. 

You can also watch a youtube example if you desire. This may help. I will increase the price for you If you can get this done. Let me know if you accept.
