Construction managers, also called general contractors or project managers, typically do the following: 1  Prepare and negotiate cost estimates, budgets, and work timetables. 2  Select appropriate construction methods and strategies. 3  Interpret and explain contracts and technical information to workers and other professionals.
Denitrification is the process that converts nitrate to nitrogen gas, thus removing bioavailable nitrogen and returning it to the atmosphere. Dinitrogen gas (N2) is the ultimate end product of denitrification, but other intermediate gaseous forms of nitrogen exist (Figure 7).
Whether anammox or denitrification is responsible for most nitrogen loss in the ocean, it is clear that anammox represents an important process in the global nitrogen cycle. Figure 6: Chemical reaction of anaerobic ammonia oxidation (anammox). Â© 2010 Nature Education All rights reserved.
