Exercise
Nitrogen Cycle: Denitrification and Atmospheric Return
In this insightful exercise, students will explore the final steps of the nitrogen cycle, focusing on the denitrification process, where bacteria convert nitrates back into nitrogen gas, returning it to the atmosphere. Through interactive activities and real-world examples, learners will understand the ecological impact of denitrification and its importance in maintaining the balance of nitrogen in our environment.
