Question
How can the nitrogen cycle cause environmental problems?
- Cause acid rain
- Deplete ozone layer
- Contribute to greenhouse effect
- Cause eutrophication in water bodies
Hint:
The release of large amounts of reactive forms of nitrogen to the environment has caused a sequence of harmful effects including ecosystem damages (loss of biodiversity, eutrophication of waters and soils, toxic algal blooms)
The correct answer is: Cause eutrophication in water bodies
- In terrestrial ecosystems, the addition of nitrogen can lead to a nutrient imbalance in trees, changes in forest health, and declines in biodiversity.
- With increased nitrogen availability there is often a change in carbon storage, thus impacting more processes than just the nitrogen cycle.
