Assess undergraduate students' understanding of terrestrial carbon cycling, focusing on key processes that control carbon fluxes (photosynthesis/NPP, autotrophic and heterotrophic respiration, litter decomposition, soil organic carbon dynamics, disturbance) and how land-use changes (deforestation, afforestation, agriculture expansion, urbanization, peatland drainage) alter carbon stocks and fluxes. Expect explanation of mechanisms, interpretation of simple NEP/NPP/respiration budgets or a short flux dataset or conceptual diagram, discussion of timescale-dependent responses and feedbacks to climate, and evaluation of common measurement and monitoring approaches (eddy covariance, chamber methods, remote sensing, carbon accounting) and mitigation options. Keep scope to terrestrial ecosystems at regional to landscape scales.
