3. FRESH WATER ZONES

4.  Shallow sunlit waters near the shore  High biological diversity  Adequate nutrients from bottom sediments LITTORAL ZONE http://www.123rf.com/photo_1470203_turtle-on-a-log-over-a-river.html http://www.google.ca/imgres?hl=en&tbo=d&biw=1366&bih=667&tbm=isch&tbnid=6CMRwBkckqVzWM:&imgre furl=http://knatolee.blogspot.com/2010_06_01_archive.html&docid=W6BTXhpqPsUtUM&imgurl=http://4.bp.bl ogspot.com/_n9d7UuYaURQ/TCCmaNVpo5I/AAAAAAAAGgM/R1laeaVaLCc/s400/Lilypads.jpg&w=400&h=289& ei=R1G- ULvEIsHx0gHYiIDYCg&zoom=1&iact=hc&vpx=1061&vpy=208&dur=437&hovh=191&hovw=264&tx=186&ty=14 1&sig=114369927815076632108&page=2&tbnh=128&tbnw=197&start=27&ndsp=32&ved=1t:429,r:51,s:0,i: 237

5.  Open shore water surface layer away from the shore  Area where the most photosynthesis occurs  Producers supply most of food and oxygen supporting the consumers LIMNETIC ZONE Pike Pickerel http://www.ontariowalleyefishing.ca/sscinclude/acloserlook.cfm/id/9569http://www.tldsb.on.ca/schools/hhss/depart/science/walleye/~walleye.htm

6.  Deep open water  Fish adapt to darker and cooler water  Too dark for photosynthesis PROFUNDAL ZONE Trout Yellow Perch http://www.environmentalhealthnews.org/ehs/news/2012 /lake-trout http://uk.wikipedia.org/wiki/%D0%A4%D0%B0%D0%B9%D0%BB:Y ellow_perch_FWS_1.jpg

7.  Bottom of the lake  Inhabited by fish that swim from zone to zone  Mostly decomposers and detritus feeders BENTHIC ZONE Bloodworm Catfish  <--Sturgeon http://www.animal-dino.com/north_american_wildlife.html http://www.dfo-mpo.gc.ca/species-especes/species-especes/green-sturgeon- esturgeon-vert-eng.htm http://www.asknature.org/strategy/2ca57cde431f462fcd1c7a7 13ca98834

8.  Impacts-  damming  transportation of invasive species by boat  transportation by motor vehicles HUMAN IMPACTS ON FRESHWATER

10.  humans need to concentrate on limiting their impacts on freshwater ecosystems  each fresh water zone is very unique and diverse in its own way CONCLUSION
