through a combination of agriculture and fossil fuel use, and unduly in uence the global nitrogen cycle.The consequences are profound for the health of both ecosystems and people.The challenge presented by the scope of the changing nitrogen cycle remains under-appreciated in both policy and scient...

(c)Ammonium ions are an important part of the nitrogen cycle. They can be converted into nitrate ions, which are used by plants and protoctists such as diatoms.(i)State the name of the molecules that are converted into ammonium ions in the nitrogen cycle.protein /urea/ amino acid;(ii) ...
The first process of the nitrogen cycle isnitrogen fixation. This is the process of converting atmospheric nitrogen into usable compounds like ammonia, nitrates, nitrites, etc. This is done via several activities. The energy generated during lightning causes oxygen and nitrogen to combine to form ni...
nitrogen cycle n. The circulation of nitrogen in nature, consisting of a cycle of chemical reactions in which nitrogen from the atmosphere is fixed in compounds in soil or water, assimilated by plants and animals, released to the soil and water through decomposition, and returned to the atmosphe...
The nitrogen cycle is the system by which nitrogen is converted into different chemical forms, some usable to humans and animals and some not, as it circulates among the atmosphere, the land and the oceans.
The ocean's nitrogen cycle is driven by complex microbial transformations, including nitrogen fixation, assimilation, nitrification, anammox and denitrification. Dinitrogen is the most abundant form of nitrogen in sea water but only accessible by nitrogen-fixing microbes. Denitrification and nitrification ar...

This is an example of a dark pattern; design that manipulates (操纵) or heavily influences users to make certain choices. Instagram uses terms like “activity” and “personalized” instead of “tracking” and “targeting,” so the user may not realize what they’re actually giving the app ...
The nitrogen forms many components like nucleic acids, proteins, amino acids etc. It is the inert gas and is the most abundant gas present in the atmosphere. It plays an important role in the fixation of nitrogen .They play a vital role in the formation of protoplasm. It is present in ...
