Exercise
Form 10: Carbon Cycle Interactions
In this engaging exercise, students will explore the intricate relationships within the carbon cycle, investigating how carbon is transferred between the atmosphere, land, and oceans through processes like photosynthesis, respiration, and decomposition. By analyzing real-world scenarios and conducting experiments, learners will deepen their understanding of carbon's pivotal role in sustaining life and driving climate change.
