Who studies Ponds and Lakes?

A person who studies

f

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
