Exercise
Ecosystem Case Studies: Forest Carbon and Nitrogen Cycles
In this immersive learning exercise, students will analyze real-world case studies focusing on the intricate relationships within forest ecosystems, specifically examining how carbon and nitrogen cycles interact to influence biodiversity and climate change. Through collaborative discussions and hands-on activities, learners will develop a deeper understanding of ecological processes and their significance in sustaining our planet's health.
