Answer;

-All of the above

-pathogens, disease vectors, and high levels of contaminants

Explanation;

Water pollution is a large set of adverse effects upon water bodies (lakes, rivers, oceans, groundwater) caused by human activities. Water pollution is caused by;

  • Increases in nutrient loading may lead to eutrophication.
  • Organic wastes such as sewage and farm waste impose high oxygen demands on the receiving water leading to oxygen depletion with potentially severe impacts on the whole eco-system.
  • Industries discharge a variety of pollutants in their wastewater including heavy metals, organic toxins, oils, nutrients, and solids.
  • Discharges can also have thermal effects, especially those from power stations, and these too reduce the available oxygen.

zhenek [66]

Answer:

The melanic or dark color type of the peppered moth was not known before pollution level was low before 1811. Hence the decrease in pollution level in atmosphere will lowers the frequency of the melanic form of peppered moths.

Thus, the correct answer is : decreases.
