Answer: In the wetland, nitrates are absorbed by plants or converted (through an anaerobic process called denitrification) to nitrogen gas and lost to the atmosphere. Nitrate-N is efficiently removed from wetland surface waters by aquatic plants. Ammonium-N enters wetlands primarily through surface runoff.
Nitrogen pollution in wetlands is processed through the nitrogen cycle involving ammonification, nitrification, and denitrification, conducted by various bacteria and fungi. These processes recycle nitrogenous waste and send it back to the atmosphere, the ocean floor, or the terrestrial food web as organic nitrogen.
Nitrogen pollution, resultant from human activities like burning of fossil fuels and use of artificial fertilizers, can be processed by wetlands through a biological process known as the nitrogen cycle. The cycle involves three steps: ammonification, nitrification, and denitrification. In the ammonification process, nitrogenous waste is converted into ammonia (NH3) by bacteria and fungi. This ammonia is then oxidized to nitrite (NO₂), and then to nitrate (NO3) in the nitrification process by soil bacteria such as Nitrosomonas. Finally, in the process of denitrification, soil bacteria like Pseudomonas and Clostridium, convert nitrate into nitrogen gas that reenters the atmosphere. Some of this nitrogen also settles into the ocean floor as sediment and becomes incorporated into terrestrial rock. Nitrogen thus processed by the wetland becomes the organic nitrogen required by the terrestrial food web.

Ian would take DNA samples from the inside of the suspects' mouths if he were asked to swab their buccal surfaces.
Identification and comparison are the two techniques forensic scientists utilize when assessing tangible evidence. Determining a substance's physical or chemical identity is the process of identification. Finding out whether two or more objects have a common origin is done through comparison.
In regard to matching, DNA analysis is comparable to fingerprint analysis. The evidence gathered at the crime scene is contrasted with a "known" print or sample when a suspect is identified using DNA or a fingerprint.
