Polluted water from a factory has flowed into a river. The water pollution will affect the river in all of the following ways EXCEPT

A)decreasing the plants that grow in water.  

B)increasing the amount of poisons in the water.  

C)decreasing the potability of the water supply.  

D)increasing the number of fish that live in the river.

The correct answer is D) increasing the number of fish that live in the river.

Water pollution means one or more substances have built up in water to such an extent that they cause problems for animals or people. Lakes and rivers can naturally clean up a certain amount of pollution by dispersing it harmlessly (water pollution is all about quantities: how much of a polluting substance is released and how big a volume of water it is released into). But chemicals in the water could very quickly have an effect on the quality of the water. And this could affect the health of all the plants, animals, and humans whose lives depend on the river. Therefore the number of fish that live in the river will probably decrease (fishes will die).

no the answer is c only objects touching the earth's surface can be acted upon by an outside force
