RUNOFF OF OIL FROM ROADS
Eutrophication is a phenomenon used to describe an INCREASE in the concentration of nutrients in a particular aquatic area (lake) leading to the proliferation of plant or algae growth. Proliferation is majorly caused by the RUNOFF of substances containing these nutrients into a water body.
According to this question, eutrophication can be caused by the following:
- Runoff of manure from farms: Manure contains nutrients that can cause an increase plant/algae growth.
- Runoff of fertilizers from neighborhood: Fertilizer contains certain elements such as nitrogen, phosphorus, potassium etc. that serves as source of nutrients for aquatic organisms.
- Excessive nutrients: Too much of nutrients lead to uncontrollable growth.
Among these options, runoff of oil from road is NOT a cause of eutrophication because OIL inhibits growth rather than induce it.
