Question

what class of water pollution can cause excessive growth of algae in waterways, depleting dissolved oxygen as the algae decays? inorganic nutrients such as nitrogen and phosphorus heavy metal pollution such as mercury and cadmium radioactive materials such as uranium and polonium pesticide pollution that cause significant mutations

Explanation:

Algae blooms are often caused by an excess of inorganic nutrients like nitrogen and phosphorus (eutrophication). These nutrients promote algae growth; when algae decay, dissolved oxygen is depleted. Heavy metals, radioactive materials, and pesticides do not primarily cause this type of algae - related oxygen depletion.

Answer:

A. inorganic nutrients such as nitrogen and phosphorus
