How does the overuse of fertilizer produce algal blooms in bodies of water far from the source of the pollution? a.Excess carbon dissolves in water and runs off into rivers and streams, causing plant and algae populations to explode.
b.Excess oxygen dissolves in water and runs off into rivers and streams, causing plant and algae populations to explode.
c.Excess nitrogen dissolves in water and runs off into rivers and streams, causing plant and algae populations to explode.
d.Excess hydrogen dissolves in water and runs off into rivers and streams, causing plant and algae populations to explode.

Answers

Answer is (c). Excess nitrogen dissolves in water and runs off into rivers and streams, causing plant and algae populations to explode.

The fertilisers contain urea which is a Nitrogen based compound. The use of fertilisers in farms leads to the water run offs carrying the excess amount of it to the nearby water bodies. The algae in the water bodies require Nitrogen to synthesise the proteins needed for their growth. The increase in the dissolved Nitrogen in the water bodies due to the run off boosts the growth of algae by fulfilling their requirements.
