resh bodies of water is a LimnologistA Limnologist is a person who studies the geographical, Physical, and other features of the fresh bodies of water.Slide3
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 waterProfundal zone - is the deep zone of the Lake or pondBenthic Zone- is the lowest level of the body of water (sea floor)Slide4
Abiotic Factors
Temperature around the lake or pond
Soil is fertileCold 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 homesSlide5
Biotic Factors
Plants
Animals
Bacteria FungiViruses P
arasitesSlide6
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.Slide7
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.Slide8
