lakes and ponds characteristics

Lake, any relatively large body of slowly moving or standing water that occupies an inland basin of appreciable size. During January and February 1981, water temperature measurements were made in lakes and ponds of Deception Island, Antarctica. These features distinguish a pond from many other aquatic terrain features, such as stream pools and tide pools. Source for information on Lakes and Ponds: Biology dictionary. Lakes, ponds, and reservoirs, as aquatic habitats, are quite distinct from rivers, creeks, and streams. Ponds can come in many different forms, and they all have their own differentiating characteristics. Oxygen is poor in the deeper waters. Ponds and lakes are distinguished from streams by their current speed. Believe it or not – kelp, seaweed, and pond scum are all different types of pond and lake algae. Then ask the children to observe characteristics of the pond plants and creatures at the end of the lesson plan. 1) made up of all the physical and chemical characteristics of the specific lake and only organ- This would include small fish which feed on algae and kelp and small turtles which also feed on kelp. They score as a lake because they can have tall waves during storms and a good sized playa lake will be deeper than twenty feet - but not always. Lakes are formed in a variety of ways, including: river activity, volcanoes, glacial activity, animal activity (Beaver dams) and human activity. Its topmost layer called is the littoral zone, it is the layer that the sun can penetrate. Pond Features. These fish feed on plankton, invertebrate organisms and sediments found in lakes. Other lakes are so big that they are called seas. This zone is the warmest since it is shallow and can absorb more of the Sun’s heat. Abstract: General characteristics of lakes and ponds, distributions, changes and sources of major ionic components (Na, K, Mg, Ca, Cl and SO4), nutrients and organic components in lake and pond waters and/or sediments of the McMurdo and Syowa Oases, Antarctica have been discussed from a geochemical viewpoint. The animals of a lakes and ponds biome contributes greatly to the maintenance of homeostasis. VINCENT* D~partement de biologie et Centre d'(tudes nordiques, Universit~ Laval, Sainte Foy G IK 7P4, Canada M.R. The topmost zone near the shore of a lake or pond is the littoral zone. 1. Lakes are much deeper compared to ponds. Without Plants nothing would live, the algae in the water oxygenates the water so the fish have the ability to live. The difference between pond and lake mainly exists in the structure of each water body and the condition of the water in it. The full text of this article hosted at iucr.org is unavailable due to technical difficulties. “Algae” are a type of protist that has plant-like characteristics and are often found in aquatic environments. Algae, like most aquatic plants, are eukaryotic organisms containing chloroplasts and are able to produce photosynthesis. About 0.009% of Earth’s water is held in lakes. Salt ponds. Thus, a lake provides an abiotic frame (Fig. Such small lakes are often referred to as ponds. Some measure only a few square meters and are small enough to fit in your backyard. Lakes and Ponds Biome: Home; Climate; Animals; Plants; Landforms; Plants. 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. Most ponds are less than six or seven feet deep. Ponds may be seasonal, lasting just a couple of months (such as sessile pools). Lakes may exist for hundreds of years or more. -The dimensions of the pond depend on the time of year. The biggest distinction is that they are inland basins where water does not flow — there isn’t a current. In this overview we hope to describe a few of the biotic (plant, animal and micro-organism) interactions as well as the abiotic interactions (physical and chemical). Human impact on water. The plants above water provide the animals oxygen to breath. The depth of these waterbodies varies between 0.88 m and 36 m, with maximum surface areas of over 290 000 m 2.Some ponds freeze completely during winter, and the lakes are covered by ice for 9–10 months of each year. Thermal stratifications occur in lakes of temperate regions. While currents in streams are easily observed, ponds and lakes possess thermally driven micro-currents and moderate wind driven currents. -They are shallow water. Lakes and ponds are divided into three different “zones” which are usually determined by depth and distance from the shoreline. Kettle ponds were created when ice chunks from glaciers were buried and later melted. Lakes and Ponds represent a freshwater biome type that is generally referred to in the scientific community as a lentic ecosystem (still or standing waters). Smaller, shallower bodies of water are often called ponds, but there is no size rule that distinguishes lake from pond. A lake or pond is a relatively still body of water. Below, you will find a discussion of some of the key types of pond ecosystem. Tennessee has more than 195,000 small lakes and ponds that provide over 97,000 acres of potential fishing waters. eyes, etc.) With proper planning and management, anglers can enjoy years of good fishing on their own property. Light in aquatic medium cannot penetrate beyond a depth of 200 meters. Abstract. A good fishing pond can also be an added source of income to landowners who let anglers fish in it for a fee. Ponds and Lakes. Individual lakes and ponds range in area from a few square meters to thousands of square kilometers. Scientists that study lakes and ponds are known as limnologists. Chloride ion contents of lake and pond waters range from 0.17 to 251 100 … The Caspian Sea, in Europe and Asia, is the world’s largest lake, with an area of more than 370,000 square kilometers (143,000 square miles). Lakes lie on land and are not part of the ocean, although like the much larger oceans, they form part of earth's water cycle.Lakes are distinct from lagoons which are generally coastal parts of the ocean.
