What effect can fertilizer runoff have on an aquatic ecosystem?
a.
increased plant growth leading to a decrease in fish populations
b.
increased plant growth leading to an increase in fish populations
c.
decreased plant growth leading to a decrease in fish populations
d.
decreased plant growth leading to an increase in fish populations

The correct answer is option a.  "increased plant growth leading to a decrease in fish populations".

Explanation:

Fertilizer runoff is an environmental concern caused by improper handling of crops by following improper gardening practices. Fertilizer runoff has a negative impact on water supplies by an increased of plant growth leading to a decrease in fish populations. Excess algae growth results in oxygen depletion which leads to an increase in the amount of nitrate-nitrogen in drinking water and a decrease in fish populations.
