What's responsible for eutrophication in seawater

Some of the causes of eutrophication of seawater are: high concentrations of inorganic matter, sudden changes in temperature, changes in the pH of water and the ability of some organisms to adapt to adverse conditions.

Explanation:

Eutrophication is the process through which lakes, streams, or bays become overloaded with nutrient-rich water. When this occurs, large blooms of algae are produced and when the algae die, microorganisms in the water feed on the remains and consequently use up the available oxygen in the water. This leaves little oxygen for fish and other aquatic animals, resulting in the suffocation of aquatic life. Some of the responsables are:
