Smith, V. H. (1982). The nitrogen and phosphorus dependence of algal biomass in lakes: an empirical and theoretical analysis. Limnology and Oceanography, 27, 1101–12. Different habitats all around the world that are made up of water combine to form the aquatic biosphere. a b "Morphological, Physiological and Anatomical Adaptations in Plants". Aligarh Muslim University . Retrieved 8 February 2022. Ponds and lakes are both stationary bodies of freshwater, with ponds being smaller than lakes. The types of life present vary within lakes and ponds. In the shallow, sunny waters there is an abundance of life, such as various species of fish. In the deep, dark waters, however, decomposers thrive. An emergent plant is one which grows in water but pierces the surface so that it is partially exposed to air. Collectively, such plants are emergent vegetation.

They include all standing water habitats. Lakes and ponds are the main examples of Lentic Ecosystem. The word lentic mainly refers to stationary or relatively still water. These ecosystems are home to algae, crabs, shrimps, amphibians such as frogs and salamanders, for both rooted and floating-leaved plants and reptiles including alligators and other water snakes are also found here.

Freshwater Biology: 358–367. doi: 10.1111/j.1365-2427.2007.01898.x.Freshwater habitat (or ecosystems) include the rivers, lakes ponds, creeks, streams, bugs, springs, swamps and wetlands. They have very low or insignificant salinity, and are much smaller in size when compared to the salt water habitat. Also, they are less deep than their saltwater counterpart. However, freshwater is more easily penetrated by sunlight, and will also contain more oxygen than marine water. With regard to habitats within freshwater ecosystems, we can distinguish them according to the movement of their currents, such as: Facts and figures on marine biodiversity | United Nations Educational, Scientific and Cultural Organization". www.unesco.org .

Kelp forests found along the coastlines of the Pacific and Antarctic Oceans also provide food and shelter for marine life. These large, brown, rubbery plants have hollow, globe-shaped growths on the leaves called pneumatocysts that help the plants rise to the surface. Sea lions, whales, shore birds, and other ocean animals make meals of the smaller critters that hide in the leaves.Helm, Rebecca R. (28 April 2021). "The mysterious ecosystem at the ocean's surface".

Some aquatic plants are used by humans as a food source. Examples include wild rice ( Zizania), water caltrop ( Trapa natans), Chinese water chestnut ( Eleocharis dulcis), Indian lotus ( Nelumbo nucifera), water spinach ( Ipomoea aquatica), and watercress ( Rorippa nasturtium-aquaticum). a b c Loeb, Stanford L.

Types of aquatic habitats

Chapman, J.L.; Reiss, M.J. (10 December 1998). Ecology. Cambridge University Press. ISBN 0-521-58802-2. Components or abiotic factors of the aquatic habitat: refers to physical, non-living factors that dictate habitat conditions, including temperature, pressure, luminosity, turbidity, salinity, and so on.

Further information: Ecosystem §Human interactions with ecosystems, Freshwater ecosystem §Threats, Marine ecosystem §Threats, and Human impact on marine life Other notable invasive plant species include floating pennywort, [41] Curly leaved pondweed, [40] the fern ally Water fern [40] and Parrot's feather. [42] Many of these invasive plants have been sold as oxygenating plants for aquaria or decorative plants for garden ponds and have then been disposed of into the environment. [40]Free-floating macrophytes are found suspended on water surface with their root not attached to the substrate, sediment, or bottom of the water body. They are easily blown by air and provide breeding ground for mosquitoes. Example include Pistia spp. commonly called water lettuce, water cabbage or Nile cabbage. [29] Morphological classification [ edit ] Here are a few things that can be done to help conserve and protect the aquatic habitat including both marine and freshwater ecosystems. The saltwater habitat is often termed as a marine habitat. On average, they have a salinity of 35ppt to 37ppt (ppt means parts per thousand). In simple terms, salinity refers to the amount of dissolved salt within a body of water. You can think of it as the concentration of salt in water. Smith, V. H. (1983). Low nitrogen to phosphorus ratios favor dominance by bluegreen algae in lake phytoplankton. Science, 221, 669–71. Those living in rivers do, however, need sufficient structural xylem to avoid being damaged by fast flowing water and they also need strong mechanisms of attachment to avoid being uprooted by river flow.
