Question
Over nourishment of water bodies due to excessive nutrients is called-
Solution
The over-nourishment of water bodies due to excessive nutrients is called "Eutrophication".
Here are the steps that lead to this condition:
-
Nutrient Load Up: Excessive nutrients that run off from the land or are piped as effluent end up in rivers, lakes and coastal environments.
-
Algae Blooms: These nutrients encourage the growth of algae and plankton, crowding out other species and creating an unsightly scum on the water surface.
-
Algae Overgrowth: As the algae continue to overgrow, they block light from other plants.
-
Oxygen Depletion: When the algae die, they sink to the bottom where they are decomposed by bacteria, using up oxygen in the process.
-
Death of Ecosystem: The lack of oxygen makes it impossible for aquatic life to survive resulting in a dead area.
This process is called eutrophication.
