Q.107
Which of the following is a common consequence of nutrient pollution in aquatic ecosystems?
- Nutrient Pollution and Algal Blooms:
- In aquatic environments, excessive inputs of limiting nitrogen and phosphorus compounds (from agricultural fertilizer runoff and untreated sewage) trigger hyper-eutrophication.
- This leads directly to rapid, explosive proliferations of microalgae and cyanobacteria known as Algal Blooms (or harmful algal blooms, HABs), causing subsequent dissolved oxygen crashes and massive fish kills.
- Correct Option: Option 2 (Algal blooms).
