Document Summary

Lecture: the hydrologic cycle moves many elements through ecosystems hydrologic cycle: movement of water through ecosystems and atmosphere; includes evaporation, transpiration, and precipitation (p: precipitation, e: evaporation, t: transpiration) Uneven distribution over land growing human population. Multiple demands for water depletion of groundwater. Current co2 levels in our atmosphere are 31% higher than the maximum concentration greenhouse effect and climate change. 25% increase of atmospheric co2 from 1958 to 2012 during the past 400,000 years. Assimilation producers take up either ammonium or nitrate consumers take up nitrogen by eating producers. Ohio is a more important source of n to the gulf than arkansas, louisiana, and. Weathering is slow, primary production relies on regeneration of nutrients from decomposition- breakdown of organic matter detritivores bacteria and fungi: in aquatic ecosystems, nutrients regenerate in the sediments. In the hydrologic cycle, infiltration refers to water from precipitation becoming part of the groundwater.
