Lakes & Ponds By: KiAndre Oliver, Brandon Bullock, Jasmyn Bednar , Jared Ruoff
Lakes & Ponds • A lake or pond is a body of water isolated (apart from) other bodies of water such as oceans or rivers. • These are aquatic ecosystems. • Lakes and ponds contain most of the worlds fresh water. • A famous lake is the “Great Lakes” located along the U.S and Canadian border. • “Lake Victoria” is the largest lake in Africaand second largest in the world located in Central Africa and serves as a border lake for Uganda, Tanzania, and Kenya.
Lakes • Most lakes are in higher or mountain areas. • Lakes are basically bigger and deeper ponds. • Usually fresh water. • Lakes have 2 layers. Epilimnion which is the higher, warmer, and has more nutrients with lots of plants and animals. Hypolimnion is the deeper, darker level with very few plants and animals.
Lakes • Some are formed by glaciers. • There aren’t any lakes in Scotland. • A dirty or polluted lake is rich with algae and is called eutrophic. Clean lakes are called oligotrophic and have small amounts of algae.
Animals & Plants in/ or by Lakes • Animals would include birds, birds of prey, fresh water fish, zooplankton, mammals such as otters or beavers, reptiles and crustaceans. • Plants include duckweed and algae as well as plants that sit beside lakes such as ferns and trees. • In shallow areas sunlight reaches the bottom and plants can grow here.
Ponds • Species in ponds include amphibians, small fish, invertebrates, crustaceans, birds/birds of prey, plankton, and amoebas(a single celled organism). • Ponds are smaller and shallower than lakes. • Temperatures are pretty even and vary depending on the temperature outside. • Very few waves.
Ponds • Ponds usually have a muddy bottom. • Plants include algae, reeds, duckweed, lillypads, small bushes, and grasses. • Ponds are basically smaller depressions of water. • Some ponds or lakes can start as a puddle that never dried but instead grew bigger. Usually they go in small basins to be a pond and bigger basin like areas to be a lake.
