Question

Why are nutrients from fertilizer harmful to aquatic ecosystems?


They cause an increase in fish populations.

The increase in algae population reduces oxygen in the water.

They can infect plants, which causes animals and humans to become sick.

Fish and other organisms grow too large and can no longer live in the ecosystem.

Answer 2

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.
