Exercise
Nitrogen Cycle: Human Impact and Fertilizers
In this engaging exercise, students will explore the nitrogen cycle by examining the vital role it plays in ecosystems and analyzing how human activities, particularly fertilizer use, can disrupt this natural process. Through interactive activities and case studies, learners will identify sustainable practices to mitigate the adverse effects of fertilizers on the environment.
