	How Ecosystems Work | Biology | Ecology  Purchase DVD here www.greatpacificmedia.com Segment from the program How Ecosystems Work: Energy Flow and Nutrient Cycles. DVD Description Looks at the processes that are fundamental to all ecosystems. First the concepts of primary productivity, trophic levels, food chains, energy pyramids and the flow of energy through ecosystems are introduced. The program then explains how carbon, nitrogen, phosphorous and water cycle through ecosystems and how human activities can disrupt these cycles and throw them out of balance leading to accelerated eutrophication in lakes in the case of phosphorous imbalances and global warming in the case of carbon imbalances. 2010年01月03日再生回数 57291
