| 1 Waters in which SAVs will grow into a mat and kill off life below are _______ | 2 Used to thin eutrophic phytoplankton growth |
| 4 This kind of eutrophication is part of ecologic succession, lasting ages | 3 Benthic plants that are entirely beneath the water surface |
| 5 Used to limit erosion, runoffs of animal wastes, and leaching of fertilizers | 6 Common limiting factor in fresh water |
| 7 Common limiting factor in sea water | 9 Used to support oxygen levels in spite of heavy draw by decomposers |
| 8 Bacteria sought by a fecal coliform test | 10 These plants anchor to bottoms of water bodies |
| 11 Benthic plants that break through the water surface | 12 Acre for acre, much worse about fertilizers than farmers |
| 13 Red Tides are an example of this | 14 Reducing this kills off overabundant shoreline plants |
| 15 Sewage that has received no treatment at all | 16 Nutrient-rich, turbid waters with phytoplankton blooms are _________ |
| 17 Clear waters with deep light penetration and low nutrients are ____________ | 18 An organism which is not pathogenic but used to test for one that is is a _________ organism. |
| 19 Only useful where SAVs have dominated instead of phytoplankton | |
| 20 Means "living on riverbanks", used with vegetation; filters water entering river | |
| 21 Some kinds exacerbate phosphorus levels in already nutrient-rich sewage | |
| 22 This kind of eutrophication is human-driven and highly accelerated |
