The nitrogen cycle is an important process by which nitrogen moves from the atmosphere into living organisms and then back into the atmosphere. Nitrogen gas (N2) makes up most of the atmospheric gas, but living things are unable to use it in this form. The nitrogen cycle uses bacteria and ...
Detritivores is branch of decomposer. It plays an essential role in most biogeochemical cycles like thenitrogen cycle,carbon cycle, and phosphorous cycle. Examples of detritivores are insects (such as mites, butterflies, mites), flies, crabs, millipedes, woodlice, earthworms, etc. Scavenger Scaveng...
The nitrogen cycle is the movement of nitrogen from the environment into living organisms and back into the environment. Nitrogen makes up about 78% of the earth’s atmosphere. It is necessary for all living organisms because it is the primary building block in proteins and DNA. The...
How does deforestation affect the biosphere? What would be the effect on living organisms if nitrogen was removed from the atmosphere? How does the carbon cycle affect the ocean? What happens to CO2 in the Calvin cycle? How does biodiversity loss disrupt the carbon cycle? What ar...

However, despite the similarity of physical and biochemical processes, ...
Although we often think of fungi as organisms that cause disease and rot food, they are vitally important to human life on many levels. As we have seen, fungi influence the well-being of human populations on a large scale because they are part of the nutrient cycle in ecosystems. They hav...
When protozoans are in the form of trophozoites, they eat bacteria that have higher concentrations of nitrogen. They release this excess nitrogen in the form of ammonium. Other organisms rapidly take up most of the ammonium, and some is utilized by plant matter. ...

They are often over-parameterized, which can give ...
This leads to the theoretical prediction that soil carbon storage is greater in ecosystems dominated by EEM fungi than in those dominated by AM fungi. Using global data sets, we show that soil in ecosystems dominated by EEM-associated plants contains 70% more carbon per unit nitrogen than soil...
