Lakes and Ponds KAYDEN LITZENBERGER AND JOSH HICKS

Who studies Ponds and Lakes?  A person who studies fresh bodies of water is a Limnologist  A Limnologist is a person who studies the geographical, Physical, and other features of the fresh bodies of water.

Diagram of Lakes and Ponds  Littoral zone - is part of the pond or lake that is close to the shore  Limnetic zone -is the open surface body of water  Profundal zone - is the deep zone of the Lake or pond  Benthic Zone- is the lowest level of the body of water (sea floor)

Abiotic Factors  Temperature around the lake or pond  Soil is fertile  Cold and warm air masses from each location mix to make an average climate  Nutrients such as Nitrogen, Carbon, and Phosphorus.  Water quality (fresh, Dirty, etc.)  Rocks or other things that Species use for homes

Biotic Factors  Plants  Animals  Bacteria  Fungi  Viruses  Parasites

Comparison between Oligotrophic and Eutrophic  Oligotrophic Lakes are those that are generally clear, deep, have low primary production, and are clean.  Definition - (oligotrophic-lacking in plant nutrients and having a large amount of dissolved oxygen throughout a lake or pond)  Eutrophic Lakes are the most productive lakes, which support a very large biomass.  Definition- rich in nutrients and so supporting a dense plant population, the decomposition of which kills animal life by depriving it of oxygen.

Canadian Example  Lake Winnipeg is considered to be the eutrophic biggest lake in the world.  Haley Lake is in Ontario not too far north of Kingston which is an oligotrophic lake.
