Lake, any relatively large body of slowly moving or standing water that occupies an inland basin of appreciable size. The main producers in pond or lake ecosystem are algae and other aquatic plants, such as Azolla, Hydrilla, Potamogeton, Pistia, Wolffia, Lemna, Eichhornia, Nymphaea, Jussiaea, etc. These "invaders" take the niches and habitats of native species. Pond and lake ecosystems are a prime example of lentic ecosystems. Lake Facts for Kids. The interaction occurs between the non-living elements such as mineral soil, water and air with the living organisms, which represents a unique system. Enjoy learning about lakes with our fun facts for kids. Read about the Great Lakes of North America, how lakes are formed, how deep lakes can get, different types of lakes, where the highest lake in the world is located, and much more. Facts about Ecosystem talk about the environment and living organisms. Altering the Ecosystem: Non-native species cause a problem in the Great Lakes ecosystem because they compete with native species for resources, which ultimately may cause native species to go extinct. A lake is an ecosystem, a community of interaction among animals, plants, microorganisms, and the physical and chemical environment in which they live. In 1998, Charlie Kerfoot discovered a "doughnut" of phytoplankton circulating in Lake Michigan, helping to feed the lake's famous fishery. The ecosystem of the Lake Tahoe Basin has been dramatically altered since European settlers began to settle around the lake in the middle of the last century. Within the global hydrologic cycle, freshwater lakes constitute only about 0.009 percent of all free water, which amounts to less than 0.4 percent of all continental fresh water. Critical to any lake ecosystem is the lake’s watershed, the surrounding land area that drains into the particular lake. Pond and Lake Ecosystems A pond or lake ecosystem includes biotic (living) plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions. The green plants convert the radiant energy into chemical energy through photosynthesis. Overview. Lentic refers to stationary or relatively still water, from the Latin lentus, which means sluggish. The relationship between the energy flows and nutrient cycles are spotted by their relationship with the biotic and abiotic components. AN example of this would be species moving from the Mississippi river into lake Michigan. A complex interdependence has evolved among the organisms in a lake community. A lake is an inland body of relatively motionless water that usually has a river or stream feeding into or draining out of it. These are either floating or suspended or rooted at the bottom.
