Explanation:

during eutrophication, there is a presence of excess algae in the water body. this causes an excess overconsumption of available organic materials by algae, causing the oxygen levels to reduce rapidly.

When the algae population grows rapidly, it may hinder sunlight from reaching other lifeforms and cause dissolved oxygen levels to fall.

What is eutrophication?

Eutrophication is the substantial increase in phosphorus, nitrogen, and other organic material in an ageing aquatic environment such as a lake.

As the amount of organic material that can be subdivided into nutrients increases, so does the efficiency or fertility of such an ecosystem.

When the algae population grows rapidly, it may prevent sunshine from reaching other organisms and cause dissolved oxygen levels to fall.

The primary environmental impacts of eutrophication are an increase in suspended particles caused by extensive macroalgal blooms, a decrease in water clarity, and an increase in precipitation rate, which has resulted in the destruction of benthic habitat due to shading of submerged vegetation.

Thus, this way, oxygen levels drop sharply during eutrophication.
