Document Summary

Diatom single cells: 2 types of benthic plants: 1. Suffocation of higher organisms, process to control it- 1. Ban phosphate detergents: 97% of the earth"s water is salt water, fresh water has a salt concentration below 0. 1, draw water cycle, indicate loop: evapotranspiration, surface runoff, groundwater, precipitation stages: 1. Adiabatic cooling- warm air rises, expands and cools, 2. 100% relative humidity is achieved and further cooling forms clouds, 3. Diminishing wetlands: falling water tables, surface runoff loop is affected by human impact through- 1. fertilizer (agriculture), 2. Storm water (surface runoff) reducing water quality: evapotranspiration loop is affected by human impact through- 1. Transportation, 4. coal burning: groundwater loop is affected by human impact through- 1. Pollution by leaching, 4. pesticide/herbicide use: climax ecosystem is when the succession reaches a dynamic balance between all species and the physical environment, the 4 major sources of carbon are- 1. Combustion of fossil fuels: major sources of phosphorus include- 1.
