The factor contributes to the carbon cycle.
Fossil Fuel combustion
Respiration
Photosynthesis
all of the above
The source of carbon to plants in the carbon cycle is
Fossil fuel
carbon rocks
atmospheric carbon dioxide
all of the above
The role of bacteria in the carbon cycle is
Breakdown of organic compounds
chemosynthesis
photosynthesis
Assimilation
In the carbon cycle, the human body returns carbon to the atmosphere through this way
formation of glucose
waste products
photosynthesis
cellular respiration
Respiration and photosynthesis are central to this process
Nitrogen cycle
Phosphorous cycle
Carbon cycle
Sulphur cycle
The difference between the phosphorous cycle and carbon cycle lies in the fact that.
the phosphorous cycle does not include a gaseous phase but the carbon cycle does
phosphorous does not enter living entities but carbon enters
the phosphors cycle includes a solid phase the carbon cycle does not
primary reservoir of the phosphorous cycle is the atmosphere, but rocks are the primary reservoirs for carbon cycle.
Most of the global warming is due to the perturbation of which of these cycles?
Global nitrogen cycle
Global carbon cycle
Global water cycle
All of these cycles equally contribute
This carbon isotope is radioactive and very rare
carbon-11
carbon-12
carbon-13
carbon-14
By this method, the majority of carbon moves from the lithosphere to the atmosphere
Erosion
Weathering
Deposition
fossil fuel burning
These entities sequester most carbon from the atmosphere
Plants
Archaea
Bacteria
Insects
