Question
What is "eutrophication" primarily associated
with?Solution
Eutrophication is a process driven by the enrichment of water by nutrients, especially compounds of nitrogen and phosphorus, which leads to excessive growth of algae and other aquatic plants. This can reduce the oxygen level in the water, severely impacting fish and other aquatic life, and is a form of water pollution.
