Document Summary

56. 1: what are the compartments of the global ecosystem: Oceans: exchange materials with the atmosphere only at their surface, respond slowly to inputs, receive material from land in river run off, upwelling zones: occur where offshore winds push water away from shore. cold bottom-water that moves up is nutrient rich and supports a high photosynthetic rate. Most of the materials enter the stratosphere at the intertropical convergence zone: a layer of ozone in the stratosphere absorbs most of the biologically-damaging. Uv radiation from the sun: most global air circulation and all water vapor is in the troposphere, the atmosphere plays a role in regulating earth"s temperature i. e. h 2o, co2, and other greenhouse gases trap the heat energy. Excess p entering lakes can cause eutrophication: excess nutrients in water stimulates the growth of algae and other photosynthesizers, when these organisms die, their decomposition by bacteria and fungi deplete dissolved oxygen.
