which can contribute toglobal warming. They can also lead to the formation of ozone in the lower levels of the environment, which can worsen chest problems like asthma. In addition, the increased growth of microbes andalgaedue to fertilizers can lead...
Describe 5 ways in which humans may intervene in the nitrogen cycle and the effects of these interventions. What does "fixation" or "to fix" mean in regards to Carbon, Nitrogen, and microbes? Briefly explain the following: Effects of increasing nitrogen and carbon dioxide on the environment. ...
Nitrogen fixationis a biological and natural process that takes place in the environment, wherein the unavailable form of atmospheric N2gas is converted into usable form of ammonia (NH3).Nitrogen fixationis a crucial process in the implementation thenitrogen cyclein the ecosystem (Barrera & Soto, ...

Even though almost 80% of our atmosphere is nitrogen, most plants and animals cannot use this atmospheric nitrogen. In order for us to be able to use this nitrogen, it must first be fixed. Nitrogen fixation is the process of creating ammonia from atmospheric nitrogen. This process is carried...

Once it enters the environment, the nitrogen in urea can trigger a spectrum of ecological impacts known as the “nitrogen cascade.” Under certain chemical conditions, and in the presence of particular microbes, urea can break down to form gases of oxidized nitrogen. These gases reach the atmosp...
Therefore, it is important to consider the impact human intake, metabolism and excretion of N-containing compounds will have on both humans and the environment. Protein was shown to be an essential source of nitrogen for humans. Other... JR Follett,RF Follett - Elsevier B.V. 被引量: 144发...
The Anthropocene has seen the influence of humans modifying the environment and the balance of the nitrogen cycle. Environmental modifications and perturbations may influence the natural processes of the capture of atmospheric nitrogen or that which is dissolved in fresh and marine waters, and the asso...
