Vedclass · Answer

(D) Eutrophication is the process in which nutrient-enriched water bodies support a dense plant population,which kills animal life by depriving it of oxygen and results in a loss of biodiversity.$A$. Excess usage of fertilisers leads to nutrient enrichment (e.g.,nitrates and phosphates),causing eutrophication.$B$. Excess usage of detergents also adds phosphates to water bodies,causing eutrophication.$C$. Dense plant population is a result/symptom of eutrophication,not a cause.$D$. Lack of nutrients is the opposite of the condition required for eutrophication.Since the question asks for the incorrect reason$(s)$,both $C$ and $D$ are incorrect as causes. However,looking at the provided options,$D$ is the most fundamentally incorrect statement regarding the cause of eutrophication.
