Because it helps give shapes and formation a little and thats why they say water is important to human beings
<span>Through the decay of tiny life forms (organic matter). For example, diatoms are microscopic single-celled algae. So their fossilized remains would be called Diatomaceous Earth. Basically, this is an organic nutrient-rich "soil" (& is used commercially as a fertilizer & as a natural pesticide- aka- Mother Nature's product w/ no harm to the environment, pets or to people).</span>
Answer:
Phosphorus is essential for growth of plants and other organisms. When concentration of phosphorus mostly from high breeding rate e.g., pigs, cattle etc. rise in water it causes severe growth of plants and algae as well as phytoplanktons. As a results layers of phosphorus start to release phosphorus as well due to positive gradient. These reactions in water are iron-redox reactions that are crucial for the release of phosphorus.
When too much phosphorus accumulates, it produces a degrading growth feedback in plants, algae and phytoplanktons that then shift toward excessive nitrogen available from fertilizers and cause a flip from P to N. Cynobacteria now dominates and denitrification as well as nitrification takes place simultaneously.
Severe eutrophication induces hypoxia in water that cause a major damage to plants biodiversity in the environment.
