Why does the increased level of nutrients in the water affect the survival of aquatic organisms?

Solution
Survival of aquatic organisms:
A surge in the amount of nutrients in the water helps aquatic animals survive because algae and many different types of plants absorb dissolved oxygen.
Overuse of chemicals (fertilizers, weedkillers, insecticides, pesticides, and so on) causes them to be carried from fields and end up in ponds, rivers, and the ocean.
These give algae the nutrients they need to flourish.
These algae decay, and the bacteria and other decomposers use them as food.
Significant amounts of the water's oxygen are used up in this process.
This causes the oxygen level of aquatic organisms to drop.
As a result, aquatic animals have a worse chance of surviving.
Aquatic creatures that utilize dissolved oxygen may be impacted by this.
