• Marine ecosystems are among the largest of Earth's aquatic ecosystems. Examples include salt marshes, intertidal zones, estuaries, lagoons, mangroves, coral reefs, the deep sea, and the sea floor. They can be contrasted with freshwaterecosystems, which have a lower salt content.
••Pollutants like oil, detergents, nitrogen and phosphate from fertilizers and lead can have a tremendous impact on the ecosystem, especially if the water gets polluted. In a lake, for example, it can wreak havoc on the ecological balance by stimulating plant growth and causing the death of fish due to suffocation resulting from lack of oxygen. The oxygen cycle will stop, and the polluted water will also affect the animals dependant on the lake water.

Water Quality's Effect on Flora and Fauna
Causes of Bad Water Quality
Water quality does not affect only humans, but it affects wildlife and plants as well. These plants and the wildlife can provide warning signs to humans on whether or not water quality is suitable for consumption.
There are many causes of bad water quality, and some of those causes are from people.
Runoff and erosion, mainly caused by heavy rain, lead to sedimentation in river systems. This sedimentation can make the water appear foggy. Usually, the little bits of sand can be slightly visible when a jar of river water after a heavy rain is scooped up. All the grains of sand will swirl within the jar of water. All of these sand grains are in that river. That is why that river is murky brown. There are other living organisms in that river. Most fish are not particulary effected. Plants can be affected due to an overabundance of nutrients from the runoff.
Not only does sediment go into water systems after heavy rain, but pesticides, herbicides, road salt and other debris, if small enough, will be carried into water systems.
Erosion and runoff are both natural processes, but with the accompaniment of these excess pollutants, will have adverse effects on plant and wildlife.
Effects on Fauna
All living organisms rely on water, in some form, for survival. Water quality does effect how long an animal is capable of surviving.
Any problems with water quality, due to their unpopularity according to a study done by Robin Boyer and Christian E. Grue. Just like with mussel species, there has also been a decline in frog species.
"All life stages of amphibians are susceptible to dermal absorption of toxicants in water. Ingestion of contaminated prey is also a potential pathway for toxicants to enter amphibians."
Effects on Flora
Plants are impacted by certain causes of bad water quality, especially sedimentation.
Sediment, in excess, can harm plant life within water systems. Sediment provides excessive amounts of nutrients from the land into water systems. This supports more algae growth, especially in stagnant, warm water, where algae will thrive. Once algae grows on the surface, it blocks sunlight from reaching the bottom of the lake or river, preventing other plants from receiving this necessary sunlight. Those plants at the bottom die away from lack of sunlight, which also means that oxygen is no longer being produced for fish and other wildlife.
The fish go elsewhere to find oxygen, leaving the algae behind to also die, because it relied on the carbon dioxide from the fish. This process is also known as eutrophication. This occurs often because of the over abundance of nutrients, caused by sedimentation.

1. There’s plenty you can do, either on your own or in a group, to make a huge difference.
2. Organise a beach clean-up.Reduce your rubbish.Make sure only rain goes down the drain.
3. Most drains flow straight to the sea … which means we could end up swimming in anything that goes down them!
4. Take care of a local stream.Find out more about your local beach.

Explanation:
Pollution is the introduction of harmful materials into the environment. These harmful materials are called pollutants. Pollutants can be natural, such as volcanic ash. They can also be created by human activity, such as trash or runoff produced by factories. Pollutants damage the quality of air, water, and land.
