UK Freshwater Habitat Types by Michael Baker https://padlet.com/michael_baker2/bsq89wntxv1p Identify and describe the main abiotic characteristics of the main types of UK Freshwater Habitats. Also identify key biological species found in each habitat. en-us 2018-01-18 22:26:52 UTC 2018-01-19 11:19:04 UTC hello@padlet.com Wetlands https://padlet.com/michael_baker2/bsq89wntxv1p/wish/222708493 What makes a Wetland
A wetland is a permanently, semi-permanently, or seasonally flooded area of land with a distinct ecosystem based on hydrology, hydric soils, and vegetation adapted for life in water saturated.

- Slow flowing 
- Commonly channeled 
- Locks - which trap areas off 
- High levels of TSS 
 - Little amounts of plant life due to the high TSS and poor light penetration 
- Substrate tends to be clay or  concrete 
-  Most suffer substantial pollution 
- Tend to be deep due to the boats

 Rivers are a large elongated water body that travels through many different counties and for miles. What make a river unique is the way that each individual section is never the same, the river bed is moulded through erosion to create a new habitat and even a new watercourse. The location of the river allows for different light to penetrate the water influencing the water. Each section is travelled through in a matter of seconds due to the high velocity of the water yet the influence that each section has on the water is still strong. This changed water go on to mould the next section and so on and so forth. Trees create shading, vegetation help life form and substrate is pushed down the river until it a slow point in which it gets deposited on the benthic layer of the river. The influenced water travels from source to mouth before entering a larger water body.  ]]> 2018-01-19 09:38:52 UTC https://padlet.com/michael_baker2/bsq89wntxv1p/wish/222709513 Lakes https://padlet.com/michael_baker2/bsq89wntxv1p/wish/222710733 Abiotic factors are the conditions or objects that affect the ecosystem and living organisms of the lake. One of the most important abiotic factors is the sun, which provides light and heat. The light helps sustain photosynthesis in phytoplanktons and aquatic plants. Temperature of the water is another important abiotic factor since several organisms in lake ecosystems are unable to regulate their body temperatures internally; therefore, they depend on the temperature of their surroundings. The temperature of the water is higher closer to the surface of the lake, while the lower zone of the lake remains cooler. In winter, a layer of ice could form over the lake and change the temperature and light availability. Wind affects the surface water of the lake and the buoyant organisms that live on it. The chemistry of the lake, such as the pH and the concentration of dissolved oxygen, also determine the type of ecosystem present.

Biotic factors include the living organisms that impact the ecosystem of the lake. Bacteria help in decomposing waste material and are present in the gut of several organisms. Lakes also have producers such as phytoplankton (for example, algae) and aquatic plants. Through photosynthesis, using light from the sun, plants produce food materials that are consumed by other organisms. Invertebrates such as zooplankton, molluscs, crustaceans and insects consume nutrients from the primary producers and pass it on to the next level of consumers, namely, the vertebrates such as fish.

Lack of thermal stratification and the presence of muddy sediments are also common characteristics of this class of water. In contrast, a "deep lake or pond" has both a shallow shoreline area that may potentially support rooted plant growth and a deeper portion where sunlight does not penetrate to the bottom. These waterbodies frequently stratify into distinct thermal layers during the summer. - New Hampshire department of environmental services.

BASC state that "A pond can be defined as a man–made or natural water body between 1m2 and 2ha in area which holds water for more than four months of the year.

steams have high erosion rates which prevents organic matter like leaves to be held in rivers they generally get flushed through. streams are know to be lacking nutrients for this reason, but minerals levels are increased due to the erosion of rocky substrate (depending on location). 
due to the size of a stream the temperature changes is not uncommon due to volume found.

the species found are much less greater that rivers due to the productivity which is low in streams. 
stoneflies, mayflies and caddisflies, which are hunted by salmon and brown trout, and birds like dippers are present along with bull head, minnow and other small telieosk fish species. ]]> 2018-01-19 09:51:00 UTC https://padlet.com/michael_baker2/bsq89wntxv1p/wish/222712799 Reservoirs https://padlet.com/michael_baker2/bsq89wntxv1p/wish/222712911 A reservoir is an artificial lake where water is stored. Most reservoirs are formed by constructing dams across rivers. A reservoir can also be formed from a natural lake whose outlet has been dammed to control the water level. The dam controls the amount of water that flows out of the reservoir.
