Answer 1

Which type of human activity increases the amount of nitrogen in bodies of water?

Option D) Fertilizing crops​

Answer 2

The correct answer is D. Fertilizing crops.

Why?:

Fertilizing crops is a common agricultural practice that can cause an increase in the amount of nitrogen in bodies of water. Nitrogen from fertilizer can run off into rivers and lakes, leading to increases in the amount of nitrogen present in aquatic ecosystems. This can lead to algae blooms and other changes in the ecosystem, which can negatively impact local wildlife.
