Answer :
Nutrients from fertilizers are harmful to aquatic ecosystems because fertilizers are often high in nitrogen and phosphorous which cause problems in aquatic ecosystems. These chemicals lead to algal blooms which causes algae to die faster and decompose thus reducing the oxygen content of the water and also hurting other organisms within the aquatic ecosystem as a result.

B. The increase in algae population reduces oxygen in the water.
Explanation: if ody ssey, it wants the answer from assignment 12 page 2 paragraph 2. Under Water Pollution.
