now let's study eutrophication.
1.what is eutrophication?
It is a state of excessive nutritional enrichment as organic matter or other kinds of nutrients flows into the water in high quantity, rendering self-purification of river or worthless. It is one of the most common types of water pollution.

2. eutrophication process
a rise in nutrient concentration - a suegein algae or phytoplankton population. *algae and phytoplankton die after active breeding during their short lifespan - decomposition of dead algae and phytoplanktona -  oxygen consumed during decomposition process - oxygen shortage kills fish, releasing odor and turning water turbid.
rising nufrient concentration - increased algae and phytoplankton popupation | algae and phytoplanktion have short livespan so they die after active breeding
decay of perished algae and phytoplankton - oxygen consumption during decomposition
oxygen shortage kills fish releasing odor and fuming water furbid

3. what brings about eutrophication?
    if occurs when toxic chemical from synthetic detergent remaining in sewage or fertllzer in farmland flows info water supply.

4. what effect does eutrophication have?
● Reduce aquatic diversity and degrades water quality
● Make tap water stench and undrinkable
● Incur high water treatment cost
● Turn recreational activities such as swimming or fishing unsustainable
● Create an eyesore

5. seawater eutrophication
Eutrophication of seawater is referred as red tide. Such name came into existence since a sudden surge in red colored phytoplankton turns the water red. It inflicts huge damage on fish-farming and living creatures in the ocean.

    Due eutrophication many water bodies has literally death in converted in what scientist call death zones. One example is the north part of Gulf of Mexico, in the Mississippi river delta. This is because all the nutrient removal on the corn belt area, due the excessive use of fertilizers in agriculture.

    Great article. Over time, the accumulating organic material resulting from eutrophication may cause entire lakes and ponds to disappear.

    That's very true. Aquatic life suffers a lot with this.
