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 Africa and second largest in the world located in Central Africa and serves as a border lake for Uganda, Tanzania, and Kenya.

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.
5
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.
6
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.
7
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.
8
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.
