Exercise
Carbon Cycle: Decomposition and Soil Dynamics
In this engaging exercise, students will explore the vital role of decomposition in the carbon cycle by examining how organic matter transforms into valuable nutrients for soil health, ultimately enhancing plant growth and ecosystem sustainability. Through hands-on activities and interactive discussions, learners will connect the dots between decomposition, soil dynamics, and environmental balance.
