Document Summary
Bio 208 lecture 27 wednesday, march 21, 2018. How do nutrients such as carbon, nitrogen, and phosphorus cycle through ecosystems? (part two) Read ecology in action on pages 482-483 for friday. Know this stuff: energy flow vs. nutrient cycle, reservoirs, residence time, macronutrients, micronutrients, phosphorus cycle, nitrogen cycle, carbon cycle, factors influencing decomposition in terrestrial and aquatic ecosystems. Why does the proportion of herbivores: detritivores matter: nutrient cycling happens faster in aquatic systems, and faster primary production because nutrients aren"t tied to detritus, more herbivores = less detritus. In terrestrial systems, there is more detritus and slower nutrient cycling. Humans and the nitrogen cycle: changes in n cycle have affected nutrient cycling, massive amounts of n added to terrestrial reservoirs from the atmosphere reservoir because of fertilizers, haber process: artificial nitrogen fixation. Consequences: acid rain (nox): x because there are different kinds of nitric oxide that can be produced.
