provides new insight into how this process happens, through the examination of a unique species of microbe called to different concentrations of environmental resources and how those differences impacted the microbe’s nitrogen cycling ability.Tags: Sample Essays For CollegeSeven Sentence EssayCritical Thinking Activities In Patterns Imagery Logic SecondaryDiabetes Research PapersParents Doing Kids HomeworkLiterature Review On Environmental PollutionCharlotte Perkins Gilman The Yellow Wallpaper EssaysCask Of Amontillado Research PaperJe Vais Essayer Translation
(February 20, 2019): Microbes play a key role in Earth’s nitrogen cycle, helping to transform nitrogen gas from the atmosphere back and forth into organic forms of nitrogen that can be used by plants and animals.
New research from the Desert Research Institute in Reno, Nev.
As a result, marine environments are an important part of the carbon cycle and climate research.
On the ocean’s surface, marine phytoplankton (photosynthetic organisms such as plants and algae) take up carbon dioxide and nitrogen to make organic material.
When grown under low carbon concentrations, the team found that these microbes were more likely to process nitrogen by ammonification; under high carbon concentrations, denitrification prevailed.

“As we learned, the concentration of nutrients available to these microbes is what determines where the nitrogen ends up, whether it takes a pathway back towards the atmosphere or returns to ammonium,” Vuono explained.
As concerns over climate change increase, it is important for scientists to understand the cycles of Earth’s natural systems and elements.
For example, one-third of the carbon dioxide in the atmosphere, including that from anthropogenic sources, is taken up by the ocean.
By surveying various regions of the world ocean, Wrigley scientists found that these bacteria are actually a prominent part of ocean ecosystems.
As a result, scientists worldwide now have a new paradigm for understanding nitrogen in the ocean – and thus a better understanding of the ocean’s capability for absorbing carbon into the deep, potentially mitigating carbon dioxide in the atmosphere and climate changes on the Earth as a whole.
