Vedclass · Answer

(A) When sewage is discharged into water bodies,it introduces organic matter and nutrients like nitrogen and phosphorus. $1$. The organic matter is decomposed by microorganisms,which consume dissolved oxygen,leading to a depletion of $O_2$ levels. $2$. The excess nutrients promote the growth of algae,leading to algal blooms (often Cyanophycean blooms). $3$. This process of nutrient enrichment and subsequent biological changes is known as eutrophication. $4$. Therefore,the discharge of sewage leads to a decrease in $O_2$,not an increase.
