Fig6: Aquatic Ecosystem. ; Wetlands are habitat to aquatic flora and fauna, numerous species of native and migratory birds. Aquatic ecosystems perform many important environmental functions. dissolved oxygen and salt in the water are important. For example, trees provide shade whilst forests influence rainfall and water availability both locally and regionally. As a result, aquatic ecosystems are divided into freshwater ecosystems and marine ecosystems. Unit 5: Pollution: Water, Air, and Land Chapter 11: Water Environmental Science: Holt pages 288-313 Below you find the classroom assignments and PPT's used for Chapter 11, Water.

The freshwater ecosystems they are one of the types of aquatic ecosystems that exist on planet Earth. 14. Freshwater ecosystems can be divided into three main categories: rivers and streams, lakes and ponds, and freshwater wetlands. The main factor which differentiates the terrestrial ecosystems from the aquatic ecosystems is the relative shortage of water in the terrestrial ecosystems and as a result the importance that water attains in these ecosystems due to its limited availability. (c) While both cacti and water lilies prefer exposure to full sun, bunchberries are adapted to shade. Services that help to support production of harvestable goods can be considered services to agriculture (Zhang et al., 2007).These services include soil structure and fertility enhancement, nutrient cycling, water provision, erosion control, pollination, and pest control, among others (Figure 2). The ecosystem which is found only on landforms is known as the terrestrial ecosystem. • Bacteria live in the deep areas of freshwater. The frequent rainfall washes away nutrients, making the soil not very fertile. Naturally fast-flowing streams usually have clearer water and higher oxygen content than slow-flowing streams. In biology and ecology, abiotic components or abiotic factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems. Ecosystems also represent an … Abstract: Aquatic environments are under increasing stress due to human activities. Some important characteristics of the marine ecosystemare: 1. Importance of aquatic ecosystems Biodiversity  Species richness/trophic structure Breeding  Breeding grounds for many species Buffer systems  Physical and chemical Sinks  Resting places for sediments and chemicals Only part of … A wetland is a habitat that is inundated by water at least some of the time and that supports plants adapted to water-saturated soil.

They These include terrestrial, or land-based, ecosystems, The nutrients provided by fish aid in the development of other organisms and helps regulate the ecosystem's food web. For example, they recycle nutrients, purify water, attenuate floods, recharge ground water and provide habitats for wildlife.Aquatic ecosystems are also used for human recreation, and are very important to the tourism industry, especially in coastal regions. By air, and water pollution, drinkng water sources can become stagnent and undrinkable; By taking steps to conserve the aquatic ecosystem and water, there wouldn't be a sustainable ecosystem.

The marine waters may be fully saline, brackish or nearly fresh. In addition to being essential contributors to biodiversity and ecological productivity, they also provide a variety of services for human populations, including water for drinking and irrigation, recreational opportunities, and habitat for economically important fisheries. The littoral layer, near the edge of a lake, generally has a large ecosystem with organisms that can use both land and water, such as dragonflies, frogs, ducks, and turtles.

PowerPoint Presentation Last modified by: About 94% of all freshwater fisheries occur in developing countries (FAO, 2007). The types of organisms in an aquatic ecosystem are mainly deter-mined by the water’s salinity—the amount of dissolved salts the water contains. See more ideas about aquatic ecosystem, ecosystems, environmental science. Freshwater ecosystems include: •sluggish waters of lakes and ponds •moving waters of rivers and streams •Wetlands= areas of land periodically covered by water. Characteristics of Aquatic Ecosystems Factors that determine where organisms live in the water include: Ecosystems influence the local climate and air quality. The level of salinity in such zone m ay be around 0 to 5 ppt. Marine ecosystems are part of the earth’s aquatic ecosystem. Wetlands, rivers, lakes, and coastal estuaries are all aquatic ecosystems—critical elements of Earth’s dynamic processes and essential to human economies and health. 0.5 ppt and 30 ppt. The habitats that make up this vast system range from the productive nearshore regions to the barren ocean floor. Today, fishing remains the largest extractive use of wildlife in the world. Freshwater ecosystems … Aquatic freshwater habitats and wetlands, mangroves, coral reefs, arctic and alpine ecosystems, and cloud forests are particularly vulnerable to the impacts of climate change.
