Nitrogen is an element that is crucial for all living things because it is a chief component of amino acids. Amino acids make up proteins, which make up many parts of living things and do work for cells.Answer and Explanation: The nitrogen cycle is the process by which nitrogen circulates...
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. Encyclopaedia Britannica/Getty Images/HowStuffWorks Living things require nitrogen for ...
50.5K Views. Nitrogen atoms, present in all proteins and DNA, are recycled between abiotic and biotic components of the ecosystem. However, the primary form of nitrogen on Earth is nitrogen gas, which cannot be used by most animals and plants. Thus, nitr
Animals eat plants and so get their nitrogen from plant proteins. Some nitrogen is passed back to the soil as bacteria decompose animal waste. Free living nitrifying bacteria convert ammonium in the soil into nitrates. Bacteria are a vital part of the nitrogen cycle as it is because of them ...

(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 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 ...
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 ocean is home to a diverse and metabolically versatile microbial community that performs the complex biochemical transformations that drive the nitrogen cycle, including nitrogen fixation, assimilation, nitrification and nitrogen loss processes. In this Review, we discuss the wealth of new ocean nitro...
