Eutrophication
Select one:
O a. occurs when there are excess nutrients in aquatic ecosystems.
Ob restricts the O₂ supply to water below the surface.
Oc All of the choices are correct.
d. causes massive die-off of fish and invertebrates.
Oe is characterized by heavy surface algal blooms.



Answer :

Final answer:

Eutrophication is the overgrowth of algae due to excess nutrients in water bodies, leading to oxygen depletion and harm to aquatic life.


Explanation:

Eutrophication is the process by which excess nutrients in aquatic ecosystems, primarily nitrogen and phosphorus, lead to the overgrowth of algae. This overgrowth depletes oxygen as the algae die and decompose, causing harm to aquatic life and creating dead zones. The impacts of eutrophication include environmental damage, fish die-offs, and the formation of harmful algal blooms.
