SSC CHSL 2024 PYQ — Question 36

The correct answer is option 4 i.e. It happens when too much nitrogen enriches the water, causing excessive growth of plants and algae.

• Eutrophication occurs when there is an excessive enrichment of water bodies with nutrients, primarily nitrogen and phosphorus.
• This nutrient overload leads to the rapid growth of plants and algae, which can have harmful effects on aquatic ecosystems.
• The excessive algae growth, often called an algal bloom, can deplete oxygen levels in the water when the algae die and decompose, leading to the death of aquatic animals and a decline in water quality.
