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.

Answer:
In biology, osmosis is defined as the net movement of water molecules through a semipermeable membrane (e.g. cell membrane) from an area of higher to an area of lower water potential. Other definitions of osmosis are as follows:
The process of a solvent diffusing through a semipermeable membrane from an area of low solute concentration to an area of high solute concentration
The tendency of water to flow from a hypotonic solution (low concentration of dissolved substances) to hypertonic solution (higher concentration of dissolved substances) across a semipermeable membrane
In chemistry, osmosis is defined similarly. It is the passage of a pure solvent from a solution of lesser to one of greater concentration of solutes when the two solutions are separated by a membrane that selectively prevents the passage of solute molecules while allows the solvent molecules to pass through.
