This interactive PowerPoint tutorial contains 85 interactive slides that covers the topic of the Nitrogen Cycle. In this tutorial, students will learn how nitrogen cycles through the environment in series of processes (nitrogen fixation, nitrification, denitrification, assimilation, ammonification). At the end, there is a 10 question quiz to check for understanding. This is NOT a typical main idea/bullet point PowerPoint presentation. This is very much an interactive/multimedia slideshow where
