Why don’t we have a “100% rule”? 5. How would atmospheric composition change if decomposition suddenly stopped? 6. On a per area basis, what 2 terrestrial biomes have the highest NPP? On a per area basis, what 2 terrestrial biomes have the highest soil C? Why do some biomes that have low NPP have high soil C? 7. (a) What are the inputs for decomposition? What are the outputs from decomposition? (b) Refer back to question #4. Given that answer, what trophic level should be the largest contributor to
