Archaea are a major part of Earth's life and may play roles in both the carbon cycle and the nitrogen cycle.
32.
The nitrogen cycle, the phosphorus cycle, the sulphur cycle and the carbon cycle all depend on microorganisms in one way or another.
33.
Adapt-N simulates the nitrogen cycle, including nitrogen fixation, nitrification and denitrification through a combination of soil, weather, crop and field management modeling.
34.
The nitrogen cycle describes movement of the element from the air, into the biosphere and organic compounds, then back into the atmosphere.
35.
Models predicted the presence of seasonal nitrogen cycles on the moon Triton, however this has not been supported by observations to date.
36.
Almost ten years later the presence of such organisms was discovered within the " nitrospira " and the nitrogen cycle had to be updated.
37.
Nitrogen s impact on the environment is not solely determined on its form within the nitrogen cycle, but the overall concentration of each form.
38.
New aquaria often have problems associated with the nitrogen cycle due to insufficient beneficial bacteria, which is known as " New Tank Syndrome ".
39.
Nitrogen cycling is not only facilitated by grizzlies digging for food, it is also accomplished via their habit of carrying salmon carcasses into surrounding forests.
40.
They have no natural analogs due to human alterations on global climate systems, invasive species, a global mass extinction, and disruption of the global nitrogen cycle.
