(A) $BOD$ stands for Biochemical Oxygen Demand. It represents the amount of dissolved oxygen that would be consumed if all the organic matter in one liter of water were oxidized by bacteria. Sewage-polluted water contains a high amount of organic matter (biodegradable waste). As the amount of organic matter increases,the number of microorganisms (bacteria) required to decompose it also increases,leading to higher oxygen consumption. Therefore,sewage-polluted water has a significantly higher $BOD$ compared to normal,clean water.

Compared to normal water,the $BOD$ of sewage-polluted water is . . . . . . .
