Lesson 1 : This lesson describes the terrestrial carbon cycle and why it is important, including an explanation of the Greenhouse Effect.
Lesson 2 : It is important to understand how plants decompose and are constructed. This video lesson describes the anatomy of leaves and why this is important for understanding decomposition.
Lesson 3 : How does the process of decomposition work? This lesson describes how decomposition happens, and the role of microorganisms in this process.
Lesson 4 : How are predictions about carbon cycling made? This lesson describes how mathematical models are built and used to calculate the effects of climate, litter chemistry, and microbial metabolism on leaf decomposition.
