Nitrogen is the most commonly limiting nutrient in plants. Legumes use nitrogen fixing bacteria, specifically symbiotic rhizobia bacteria, within their root nodules to counter the limitation. Rhizobia bacteria convert nitrogen gas (N2) to ammonia (NH3) in a process called nitrogen fixation.

Answer:
The type of pollution demonstrated is sediment pollution.
Explanation:
- Sediment pollution is the deposition of waste products in rivers, lakes and streams by the means of soil erosion. 
- So in the abandoned construction site, sediment pollution is the major issue that causes the environment's wind and water to pollute heavily.
- The waste is swept and carried to different places that pollutes the environment badly due to the exposed construction site.
