Hello my name isAdrian I am from class 5-2 and I will be giving you some facts about the lake ecosystem

Salty or fresh, lakes are some of the only freely available water sources on land. Aside from rivers and streams, the rest of the world's freshwater is locked up in ice or trapped underground. Yet much remains mysterious about these important natural resources. Here are some new and surprising facts from a recent count of Earth's lakes, published Sept. 16 in the journal Geophysical Research Letter

=NEXT kid can help people pick u trash and
Go green,it is easier than you think. There are little things you can do every day to help reduce greenhouse gases and make a less harmful impact on the environment. Taking care of the Earth is not just a responsibility -- it's a privilege. ­In that spirit,
1.­use your water carfully. The little things can make a big difference. Every time you turn off the water while you're brushing your teeth, you're doing something good] Try drinking tap water instead of water bottles, so you aren't wasting all that packaging as well. Wash your clothes in cold water when you can.

2. Leave your car at home. If you can stay off the road just two days a week, you'll reduce greenhouse gas emissions by an average of 1,590 pounds (721 kilogram
4. Recycle.You can help reduce pollution just by putting that soda can in a different bin. If you're trying to choose between two products, pick the one with the least packaging.
5. Compost. Think about how much trash you make in a year. Reducing the amount of solid waste you produce in a year means taking up less space in landfills, so your tax dollars can work somewhere else. Plus, compost makes a great natural fertilizer.Composting is easier than you think.





PLANTS: Plants and algae are important to freshwater biomes because they provide oxygen through photosynthesis, and food for animals in this biome. In fact, that slimy scum you see on the surface of a pond or lake is lunch for many of your favorite aquatic animals, like turtles. In fast streams and rivers many plants have special structures that keep them from being carried away by the water. Some aquatic plants have strong roots that keep them anchored securely, while others have stems that bend easily with the movement of the water. Certain mosses are able to cling to rocks.

LOCATION: Lakes are large bodies of freshwater surrounded by land, while ponds are smaller bodies of water surrounded by land. Lake Baikal, in central Asia, is the biggest lake on Earth; it contains about one fifth of the Earth’s freshwater and has a maximum depth of 5,315 feet! Lake Tahoe is a huge lake on the border of California and Nevada that originates from mountain stream runoff. Most lakes are still and contain diverse plant and animal life. Rivers and streams are moving bodies of freshwater, which usually originate in mountains and come from melting ice or ground water and eventually flow into the ocean. For example, the Amazon River originates in the Andes Mountains and ends in the Atlantic Ocean. Over time, as rivers travel, they change course and carve a path through the land.

Hello my name is Terrell Pott from class 4/5-777. Here are 5 facts about my ecosystem.


1. A lake is an inland body of water that doesn't really move. All that much they usually have a river or stream that drains out of them or feeds into them.


2. They are different to lagoons but how lagoons actually connect to the ocean where lakes don't.


3. Flow- the amount of water and the strength at which it flows will impact the types of plants and animals that can live in a river.


4. Temperature - the climate of the land and the river is flowing through and it will have an impact on the ecosystem.

5. chemistry- this has to do with the type of geology that the river is flowing through it impacts what type of soil rocks and nutrients are in the river.

A Lake Ecosystem Is Made Up Of Living And Non-Living Parts That All Interact With Each Other To Form a Stable System. These Interactions Assure The Lake Ecosystem Health. It is fine Balance Production Decompostion Made Possible By The Biodiversity That Occurs In A Healthy Lake Ecosystem.
North America is home to one of the world's most remarkable ecosystems. Carved out by glaciers during the last ice age, the Great Lakes contain nearly 20% of the earth's fresh water. Only the polar ice caps contain more. This wealth of water and the glacially-sculpted landscape of the basin support a tremendous abundance and diversity of life.
As the last glaciers began retreating some 14,000 years ago, they left an ecological frontier rich in new habitats that were rapidly exploited by species immigrating from the east, south and west. These biological pioneers formed new communities that could thrive in the specialized environments created by the glaciers and sustained by the Great Lakes. As populations adapted to the special conditions in the basin, new forms of life began to evolve, further enriching the biological diversity of this unique area.
Geologically, the Great Lakes ecosystem is very young and can be thought of as an evolutionary laboratory. Species that have evolved here have done so in a remarkably short period of time, and the processes that support their continuing adaptation in this dynamic environment need to be safeguarded. Species and community types at the margins of their ranges, or with their last occurrences here, are also an important part of this evolutionary laboratory. These features are most likely to respond to environmental pressures and evolve into new forms of life that are best suited to survive in the Great Lakes ecosystem.
The lakes, and the basin that they drain, have played a major role in the history and development of the United States and Canada. The basin supports more than one- tenth of the U.S. population and more than one- fourth of the population of Canada. Nearly 25% of the total Canadian agricultural production and 7% of the U.S. agricultural production occur in the basin. Some of the world's largest concentrations of industrial capacity are located around the Great Lakes.
Human use has adversely impacted the basin ecosystem. In the last 20 years, much has been done to stem the input of nutrients and toxic chemicals into the basin, initiating a rebound in the health of the ecosystem. Although some lake communities have undergone major changes, and some species have been lost, the ecosystem as a whole still supports special biological resources. However, certain human activities continue to pose threats to the maintenance of biological diversity in the Great Lakes basin.

Temperature :

Temperature Is An Important abiotic Factor in lentic Ecosystems because most of biota are poikilotthermic, where internal body temperatures are defined by the surrounding system. Water can be heated or cooled through radiation at the surface and conduction to or from the air and surrounding substrate
(Giller and Malmqvist 1998). Shallow ponds often have a continuous temperature gradient from warmer waters at the surface to cooler waters at the bottom. In addition, temperature fluctuations can be very great in these systems, both diurnally and seasonally (Brown 1987).
Temperature regimes are very different in large lakes (Fig. 2). In temperate regions, for example, as air temperatures increase, the icy layer formed on the surface of the lake breaks up, leaving the water at approximately 4 °C. This is the temperature at which water has the highest density. As the season progresses, the warmer air temperatures heat the surface waters, making them less dense. The deeper waters remain cool and dense due to reduced light penetration. As the summer begins, two distinct layers become established, with such a large temperature difference between them that they remain stratified. The lowest zone in the lake is the coldest and is called the hypolimnion. The upper warm zone is called the epilimnion. Between these zones is a band of rapid temperature change called the thermocline. During the colder fall season, heat is lost at the surface and the epilimnion cools. When the temperatures of the two zones are close enough, the waters begin to mix again to create a uniform temperature, an event termed lake turnover. In the winter, inverse stratification occurs as water near the surface cools freezes, while warmer, but denser water remains near the bottom. A thermocline is established, and the cycle repeats (Brown 1987, Brönmark and Hansson 2005).

Lake Ecosystem Summary

By Zuleima Baez, Tabitha Guzman, Celia Irizarry

A lake ecosystem is made up of living and nonliving parts that all interact with each other to form a stable system. These interactions assure the lake ecosystem’s health and sustainability. It is a fine balance of production and decomposition, made possible by the biodiversity that occurs in a healthy lake ecosystem.
Lake ecosystem
An ecosystem is the interaction of the living and non-living elements of a particular environment such as lakes. ocean. forest or meadow.
A lake is an ecosystem all in itself. It contains zones based on the light penetration. Not based on the fish and zooplankton that inhabit the lake. The coastline area of a lake that is permanently under water comprises the littoral zone. In this zone sunlight reaches the bottom of the lake. The temperature of this zone is greatly impacted by weather.
  • Goldfish have been reported to have a memory that lasts less than three seconds. However, in February 2008, the Daily Telegraph stated that an Australian student proved that theory incorrect. The student, Rory Stokes of the Australian Science and Mathematics School, placed a beacon in a tank with food once a day for three weeks. The goldfish ate the food until the beacon was completely removed from the tank for a period of six days. Then, when the beacon and food were returned to the tank, the goldfish immediately went to the beacon, indicating that they did recall the food source for nearly one week This experiment can be used as the basis for further research to determine how long the memory of a goldfish is by removing the beacon for increasingly longer periods of time.

Maze

  • Goldfish can communicate with one another, as well as manipulate a maze, if necessary, to find food. Students in the higher grade levels can prove this fact through using their own ingenuity to build a maze inside of an aquarium and placing a lone goldfish in the water. As time progresses the students will discover that the goldfish will attempt to manipulate the maze and eventually find the food source. NECN.com reports that one high school student in New England found that after her first goldfish was capable of making its way through the maze, that same goldfish then assisted a second goldfish in finding its way through the maze as well. Students should take notes on a daily basis on the progress of the experiment and compare the results of the project with his or her original hypothesis.

A lake is a body of relatively still fresh or salt water of considerable size, localized in a basin that is surrounded by land. Lakes are inland and not part of the ocean, and are larger and deeper than ponds.[1][2] Lakes can be contrasted with rivers or streams, which are usually flowing. However most lakes are fed and drained by rivers and streams.
Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers. In some parts of the world there are many lakes because of chaotic drainage patterns left over from the last Ice Age. All lakes are temporary over geologic time scales, as they will slowly fill in with sediments or spill out of the basin containing them.
Many lakes are artificial and are constructed for industrial or agricultural use, for hydro-electric power generation or domestic water supply, or for aesthetic or recreational purposes.
