Give you a conclusion for thermal pollution?
'''Thermal pollution''' is the rise or fall in the temperature of a natural body of water caused by human influence. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. When water used as a coolant is returned to the natural environment at a higher temperature the change in temperature impacts organisms by (a) decreasing oxygen supply, and (b) affecting ecosystem composition. Urban runoff--storm water discharged to surface waters from roads and parking lots--can also be a source of elevated water temperatures
What are the advantages and disadvantages of thermal pollution?
the advantage is that the plants can give out more oxygen in day time .may be we will be healthy. the disadvantage is that our surrounding may be polluted and not clean.
Where is thermal pollution happening?
It is caused by addition of hot effluents and hot water bodies. Warm water contains less oxygen. So there is decrease in rate of decomposition of organic matter. Green algae are replaced by less desirable blue green algae. Many animals fail to multiply. Trout eggs fail to hatch while salmon does not spawn at higher temperature.
The major factors which determine aquatic biomes are?
hydrogen, oxygen, and temperature
Is oxygen conductive?
The thermal conductivity of oxygen is 24,24 mW/mK at 1,013 bar and 0 0C.
How cutting tree affect the rate of pollution in such ecosystem?
Trees produce oxygen. If the tree is cut down, it will no longer produce the oxygen that the ecosystem needs. So when we cut down trees, less oxygen is being produced, and the less oxygen produced, the more uneven the balance of pollution and oxygen.
What is a type of pollution that occurs when industries dump hot water into bodies of water?
Thermal pollution results from adding heated water to a watercourse. Thermal pollution encourages the growth of some aquatic organisms over others (e.g. trout need colder water than carp) and reduces the oxygen content of the water so that only more resistant life forms can live in the water.
What is trimal pollution?
First it's Thermal Thermal pollution is a temperature change in natural water bodies caused by human influence. The temperature change can be upwards or downwards. In the Northern Hemisphere, a common cause of thermal pollution is the use of water as a coolant, especially in power plants. Water used as a coolant is returned to the natural environment at a higher temperature. Increases in water temperature can impact on aquatic organisms by (a) decreasing oxygen supply, (b) killing fish juveniles which are vulnerable to small increases in temperature, and (c) affecting ecosystem composition. In the Southern Hemisphere, thermal pollution is commonly caused by the release of very cold water from the base of reservoirs, with severe affects on fish (particularly eggs and larvae), macroinvertebrates and river productivity.
What is Total Oxygen Demand TOD?
The amount the organism within a community, particularly in an aquatic community, demend oxygen. Eutrophication can cause the demand to rise and harm the fish within the aquatic ecosystem.
Why are fish most likely to be harmed by long term thermal pollution of the lake in which they live?
Because thermal pollution increases water temperature, so decreasing oxygen availability for the organisms in the lake.
Thermal pollution kill fish primarily because?
Warm water holds less oxygen
When too many nutrients are added to an aquatic ecosystem the devastating result is?
eutrophication. This can lead to excessive growth of algae and other aquatic plants, which can deplete oxygen levels in the water. This depletion of oxygen can harm fish and other organisms, leading to a decline in biodiversity and, in some cases, the complete collapse of the ecosystem.
Why is oxygen bad in water?
Cold water can hold more dissolved oxygen than warmer water.
How eutrophication can change an aquatic ecosystem into a land ecosystem?
Some changes that can occur in the aquatic ecosystem as a result of nutrient loading is called algal bloom. This is where there is a rapid increase of growth of phytoplankton which causes dead zones. These dead zones consume too much oxygen where plants and sea life can no longer survive in these areas.

How does seasonal turnover in lakes affect oxygen level available to the aquatic organisms?
It affects the oxygen level because it is essential for the survival and growth of organisms ata ll levels within its ecosystem.
Power plants that discharge warm water into rivers have a negative effect on aquatic life This is because the higher water temperature?
It decreases the dissolved oxygen in the river water Answer: Thermal (warmer water) pollution:* Lowers the oxygen saturation point of the water making it less desirable for non tolerant species (Carp flourish, trout don't) * Promotes the growth of slimes and molds * Changes the rate of decomposition * Prevents breeding of some fish species * Changes the benthic population * Promotes overwintering of some bird species
