Lakes and PondsKAYDEN 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.
