In pond water how much does plant life help/hurt microorganisms?

Many of the microorganisms in the pond water are actually plants.\n\nThe microscopic organisms living in the water column are usually refered to as plankton.  The phytoplankton are the microscopic plants, while the zooplankton are the microscopic animals.  The phytoplankton are the majority of the mass, mostly single celled algae and diatoms.

possible but its more on the no side, conditions not right for life, even for microorganisms that can take extreme temperatures and harsh environment...best of all...no water, its all ice caps!

well, i do know there's this blue chemical called biochemical oxygen demand(BOD) which is used to see how polluted water is from different sources. like, if you compare drain water and pond water. so if you put few drops in each water, and wait for one day, you'll realise that drain water isnt as blue as pond water coz drain water is more polluted. since there are more waste compared to pond water, so there'll be less oxygen. so yeah.

If there were high nitrate levels... the lake would eventually become a wetland or swamp.  Plants like nitrates... aquatic life does not.  Some lakes are suffering from nitrate run-off (it usually comes from farmers fields or where other types of nitrogen rich fertilizers or substances aren't kept in check)  Those nitrates then in turn generate weed growth.  The weed growth will then choke off the lake.  Ever notice the wierd shade of green in a pond next to houses or apartment complexes.  They're using chemicals to keep the water's P-H on the acidic side to curb vegetation and maintain the proper aesthetics that they want of open water.  If you want further information pertaining to your more immediate area... contact your local county agricultural agent.  He or she should be listed in the white pages under county government.

Try this website, it has some good explanations of things like total dissolved solids, dissolved carbonates, boron, and other things often found in water used for growing plants. There's even a little information that is specific to grasses. \nhttp://www.ext.nodak.edu/extpubs/ageng/irrigate/eb66w.htm#plants\n\nBy the way, I found this using the search terms:\nirrigation water\nSo if you want to duplicate my search and see other results this should get you going.

Good Question:\n\nParamecium eat bacteria.

Yes, actually if you water the plants too much the roots gets rotten and die, on the other hand if you don't water the plants they also die, so it has to be a balance, water moderate once a day and plenty of sunlight, that's the idea..☺

Depends on the country. Here in the US our water is relatively bacteria free, but other countries.........well, DON'T DRINK THE WATER!!

There's lots of different effects of pollution. Very few pollutants directly kill creatures in the water, unless they're released in huge amounts because they're simply not strong enough. What they usually do is disrupt the ecosystem that then kills most of the creatures.\nExamples:\nOil - creates a film on the water which blocks the passage of gasses in and out of the water. CO2 builds up in the water and kills most of the marine fauna. (this can also kill the terra life, birds and animals which also add to the pollution of the water) These rotting creatures increase the amount of nitrogen and nutrient in the water which encourage bacterial and algae blooms in the water. These particles in the water then block the light which kills the water flora. If the pollutants stay in the water and can not be flushed out then they encourage the build up even more organic matter around the waterway, and this restricts the flow of the water even more. The natural disruption of this cycle is flooding, which breaks up and washes away the toxins and debris to the ocean, which is much better able to recover from these processes. This process is less common now due to wide spread control of waterways with damming and irrigation. Many first world countries artifically recreate this process artifically by periodically flushing the river.\n\n(although our oceans are now getting in trouble too because many of the toxins we use don't break down, so over time they gradually build up and litterally have nowhere to go)\n\nAnother example is nitrogen pollution (cleaning products) which do a similar process, but they directly encourage bacterial and algae blooms... then you can take it from there.\n\nHeavy metals pollution is a little different. It builds up in a system and as it's heavier, it mostly sinks to the bottom of the river and is difficult to flush out, remaining for many generations. Smaller particles are consumed by the ocean life (eg, fish eating worms that each have a small amount in their system, then birds/humans/other animals eat the fish and the toxins are transported to the land.) This usually makes everything very sick, putting strains on any already stressed populations. This has a less dramatic effect, but much longer lasting results.\n\nI hope this helped.

For aquariums?  Chlorine can be neutralized with sodium thiosulfate... you may be able to find this at a supply place, but not much more convenient than the regular aquarium stuff.  Ascorbic acid (vitamin c) will also do it, but i'm not sure alot of AA in the water is good- might promote fungus or something.  Don't gamble on the ick stuff, even a slight mis-dose or mis-formulation could result in dead fish.  You are basically making the water just toxic enough to kill the fungus without killing Cecil.

Nothing.  Except have a lower water volume due to warmer water molecules converting to gas.  However, the warmer water may have an efffect on the plants you are studying.  If you water a plant with hot water it may kill the plant.

Water is the basic solvent in the nature .In its presence only the biochemical reactions takes place(like photosynthesis, respiration, fat metabolism)\nAbove all water gives turgidity to plants ,with out water plants will wilt  and die, this is what happens when u do not water the plant for a long time

A lot of the water came from the river in the first place. There is a net loss through plants, evaporation so I can't imagine why there is a problem of excess. sometimes the water is hotter so fish, plants have trouble.\nWhy if it is so clean, do plants get more river water instead of their "clean" water?

Well, that depends.  There is evidence of algae at 3.5 billion, probably photosythetic cells by 2.0, and clear plants by 400 million.  With a 4.6 billion year old earth, that's 76%, 43%, or 8.7% of the time.

A paper writen by Karen Manci, Ohio State Univ, College of Food and Evironmental Sciences is helpful:\n\nWastewater Treatment Principles and Regulations\nAEX-768-96\n\nSewage is the wastewater released by residences, businesses and industries in a community. It is 99.94 percent water, with only 0.06 percent of the wastewater dissolved and suspended solid material. The cloudiness of sewage is caused by suspended particles which in untreated sewage ranges from 100 to 350 mg/l. A measure of the strength of the wastewater is biochemical oxygen demand, or BOD5. The BOD5 measures the amount of oxygen microorganisms require in five days to break down sewage. Untreated sewage has a BOD5 ranging from 100 mg/l to 300 mg/l. Pathogens or disease-causing organisms are present in sewage. Coliform bacteria are used as an indicator of disease-causing organisms. Sewage also contains nutrients (such as ammonia and phosphorus), minerals, and metals. Ammonia can range from 12 to 50 mg/l and phosphorus can range from 6 to 20 mg/l in untreated sewage. \n\nSewage treatment is a multi-stage process to renovate wastewater before it reenters a body of water, is applied to the land or is reused. The goal is to reduce or remove organic matter, solids, nutrients, disease-causing organisms and other pollutants from wastewater. Each receiving body of water has limits to the amount of pollutants it can receive without degradation. Therefore, each sewage treatment plant must hold a permit listing the allowable levels of BOD5, suspended solids, coliform bacteria and other pollutants. The discharge permits are called NPDES permits which stands for the National Pollutant Discharge Elimination System. \n\nPreliminary Treatment\nPreliminary treatment to screen out, grind up, or separate debris is the first step in wastewater treatment. Sticks, rags, large food particles, sand, gravel, toys, etc., are removed at this stage to protect the pumping and other equipment in the treatment plant. Treatment equipment such as bar screens, comminutors (a large version of a garbage disposal), and grit chambers are used as the wastewater first enters a treatment plant. The collected debris is usually disposed of in a landfill. \n\nPrimary Treatment\nPrimary treatment is the second step in treatment and separates suspended solids and greases from wastewater. Waste-water is held in a quiet tank for several hours allowing the particles to settle to the bottom and the greases to float to the top. The solids drawn off the bottom and skimmed off the top receive further treatment as sludge. The clarified wastewater flows on to the next stage of wastewater treatment. Clarifiers and septic tanks are usually used to provide primary treatment. \n\nSecondary Treatment\nSecondary treatment is a biological treatment process to remove dissolved organic matter from wastewater. Sewage microorganisms are cultivated and added to the wastewater. The microorganisms absorb organic matter from sewage as their food supply. Three approaches are used to accomplish secondary treatment; fixed film, suspended film and lagoon systems. \nFixed Film Systems\nFixed film systems grow microorganisms on substrates such as rocks, sand or plastic. The wastewater is spread over the substrate, allowing the wastewater to flow past the film of microorganisms fixed to the substrate. As organic matter and nutrients are absorbed from the wastewater, the film of microorganisms grows and thickens. Trickling filters, rotating biological contactors, and sand filters are examples of fixed film systems. \n\nSuspended Film Systems\nSuspended film systems stir and suspend microorganisms in wastewater. As the microorganisms absorb organic matter and nutrients from the wastewater they grow in size and number. After the microorganisms have been suspended in the wastewater for several hours, they are settled out as a sludge. Some of the sludge is pumped back into the incoming wastewater to provide "seed" microorganisms. The

think of it as a bacteria...bacteria is a living organism...if you disinfect it will it not die?does bacteria think?does bacteria feel pain and what not?\n\nveggies live off water/sun/nutrients just as we do.veggies begin to rot bebore dead/wasted.\nhumans rot after death...\n\nwhat will you do?\nwhat will you think?
