D. The nitrogen from the fertilizer made the plants grow too quickly,
which hurt the fish.
Explanation:
The best explanation for this result is that the nitrogen from the fertilizer caused the plants to grow too quickly and this hurts the fish.
This phenomenon is known as eutrophication.
Eutrophication is condition in which too much of nutrient is available in a water body.
- The presence of the fertilizer in the water body causes nutrient availability that causes more plants to grow in the water.
- The surge in the plant population will starve other life forms in the water.
- This is why the number of fishes will reduce.

Explanation:
Groundwater is water that occupies the zone of saturation within the ground. The water table is the upper limit of the groundwater. An aquifer is a body of porous rock or sediment saturated with groundwater. Groundwater enters an aquifer as precipitation seeps through the soil. It can move through the aquifer and resurface through springs and wells. Groundwater separated from atmospheric pressure by relatively impermeable material is termed confined groundwater. When such zones are penetrated by wells, the water rises above the point at which it was first found because a confined aquifer is under pressure exceeding that of atmospheric pressure.
