  1. Fresh water life zones Sonny, Eric, Daniel, Shannon

  2. Table of contents • Fresh water zone introduction • Littoral Zone • Limnetic Zone • Profundal Zone • Benthic Zone • Human Impacts on Freshwater • Conclusion • References • Table of contents

  3. Fresh water zones

  4. Littoral Zone • Shallow sunlit waters near the shore • High biological diversity • Adequate nutrients from bottom sediments http://www.google.ca/imgres?hl=en&tbo=d&biw=1366&bih=667&tbm=isch&tbnid=6CMRwBkckqVzWM:&imgrefurl=http://knatolee.blogspot.com/2010_06_01_archive.html&docid=W6BTXhpqPsUtUM&imgurl=http://4.bp.blogspot.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=141&sig=114369927815076632108&page=2&tbnh=128&tbnw=197&start=27&ndsp=32&ved=1t:429,r:51,s:0,i:237 http://www.123rf.com/photo_1470203_turtle-on-a-log-over-a-river.html

  5. LIMNETIC ZONE • 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 Pike Pickerel http://www.tldsb.on.ca/schools/hhss/depart/science/walleye/~walleye.htm http://www.ontariowalleyefishing.ca/sscinclude/acloserlook.cfm/id/9569

  6. Profundal zone • Deep open water • Fish adapt to darker and cooler water • Too dark for photosynthesis Yellow Perch Trout http://uk.wikipedia.org/wiki/%D0%A4%D0%B0%D0%B9%D0%BB:Yellow_perch_FWS_1.jpg http://www.environmentalhealthnews.org/ehs/news/2012/lake-trout

  7. Benthic zone • Bottom of the lake • Inhabited by fish that swim from zone to zone • Mostly decomposers and detritus feeders Catfish Bloodworm http://www.animal-dino.com/north_american_wildlife.html <--Sturgeon http://www.asknature.org/strategy/2ca57cde431f462fcd1c7a713ca98834 http://www.dfo-mpo.gc.ca/species-especes/species-especes/green-sturgeon-esturgeon-vert-eng.htm

  8. Human impacts on freshwater • Impacts- • damming • transportation of invasive species by boat • transportation by motor vehicles

  9. RIGGERS http://www.team-fishigan.com/FT/boat_rig/boat.htm

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