The definition of eutrophication, as SPC had asked, is the rapid growth of certain plant species, normally those growing on the surface (such as algae), because of excessive plant growth enhancement chemicals (fertilizers) present in the water body. These fertilizers are present because of run-off from nearby farms, or illegal dumping.
Effects of EUTROPHICATION:
1) Imbalance of oxygen levels. [COMPULSORY]
The fertilizers will form a layer somewhere below the surface, called the PYCNOCLINE LAYER. This layer is thick and blocks oxygen to the area underneath it; hence animals (especially IMMOBILE animals) living below suffocate and dies.
2) Enhanced growth of bacteria. [related to Imbalance, but NOT COMPULSORY]
As you know, bacteria need not have oxygen to respire, hence the word ANAEROBIC. Mentioned above, the PYCNOCLINE LAYER blocks oxygen, and will promote the growth of such bacteria. One worrying issue is that the Clostridium Botulinum (you know this during HomeEc) bacteria will thrive and infect the water body and the organisms. In the end, we humans will be affected.
3) Death. [related to Imbalance]
If there is no oxgen deep below, organisms suffocate and die. A few days after they had died, their corpses will begin to rot and stink up the whole water body, making it so much like hell that we humans can't use it.
4) Ravaged ecosystem.
As said above, organisms die, and consumers may follow suit (no food). Because of the increase in the chemicals, or rather, imbalance in the chemical proportion of the affected water body, new species may enter the ecosystem and disrupt the whole ecosystem till it becomes something like your desk.
5) Toxins.
This is also rather worrying. The increase in the amount of fertilizers and chemicals may enhance a species of harmful alga that have toxins. Consumers of the alga may be poisoned. If we happen to eat that consumer, it's Good Luck Have Fun to us.
A good example is the shellfish poisoning incident (Shumway 1990).
That's all. If there are any problems with anything, please inform me ASAP. I don't want to cause anybody to fail their test.
