This is the official answer key for our website's "Carbon and Nitrogen Cycle" handout. The "Carbon and Nitrogen Cycle" handout for students is available for free on our website www.AmoebaSisters.com/handouts and uses our "Carbon and Nitrogen Cycle" Amoeba Sisters video from YouTube. Please verify that you have the matching student handout from our website that this key accompanies. By purchasing our answer key for less than the price of a typical specialty coffee drink, you are helping fund our passion in creating science videos, GIFs, comics, handouts, and more!
Note: This answer key is included in the purchase of our 9 Variety Topics Answer Key Bundle!
We thank you for your support and for watching our videos! We try our best to screen for all typos in our answer keys, but we are amoebas (er, human). If you ever find a typo or problem with our key, please let us know! We want to fix it and then give you a new replacement copy.
Terms and Conditions of Use for Amoeba Sisters Answer Keys:
This answer key is intended for educator use. Answer keys may not be distributed, reproduced, or sold by any individual or outside entity.
No form of this handout or its copyrighted text can be made available publicly online or distributed publicly in print. Public availability of Amoeba Sisters answer keys is a violation of copyright, and it is also a disservice to other educators who wish to use our activities. Modification of this document is prohibited.
We have an unusual style in that all of our videos are free as well as our free student video recap handouts from our website (with the exception of “select handouts” available only on TPT). The keys take a substantial amount of time to create as you will notice that the answers are very thorough and often need to address open-ended responses. We calculate our time in the price. We love specialty coffees, and we figure that if we can set EACH answer key at a price at—or a bit less--- than what you may spend on 1 specialty coffee drink, then this seems reasonable as all other components we create are already free. Keys can offer convenience as well as be helpful if you are new to the content. Our answer key bundles combine keys, and we set bundle prices lower than if you were to purchase them all individually.
