What does the Redfield ratio tell us?
The Redfield ratio is the ratio in which different chemical elements are present in average phytoplankton biomass. It defines the stoichiometry of photosynthesis and remineralization reactions.
What is the Redfield ratio of C Si N P?
The Redfield Ratio is the recurring ratio of 106:16:1 of carbon to nitrogen to phosphorus (C:N:P) found in marine phytoplankton.
What is the Redfield ratio quizlet?
Redfield ratio. 106:16:1 ratio of C:N:P which under optimal growth conditions is the amount removed by phytoplankton from seawater; it is also the amount released back into seawater when an organism dies and decomposes.
Why are continental margins more biologically productive than the open ocean?
Why are continental margins more biologically productive than the open ocean? There are more available nutrients along the continental margins. In temperate oceans of the northern hemisphere during the winter months: Nutrient concentrations are high, solar input is low, and water temperatures decrease.
In what part of the oceans is sunlight limiting the amount of primary productivity?
the Arctic Ocean
Reduction of sunlight by sea ice is a major limiting factor for primary productivity in the Arctic Ocean.
In what molar ratio does marine organic matter typically contain carbon nitrogen and phosphorus?
A C:N:P. of 106:16:1 in POM, the so-called Redfield ratio, has been fundamental in marine biogeochemistry for nearly a century (7, 8).
What does CNP mean?
What does CNP stand for?
| Rank Abbr. | Meaning |
|---|---|
| CNP | C-Type Natriuretic Peptide |
| CNP | Clinical Nurse Specialist |
| CNP | Certified Nurse Practitioner |
| CNP | Chief of Naval Personnel |
What would be a good ratio of C’N p of your feed wastewater If you want to treat it with microorganisms?
This is crucial to the effectiveness of the biodegradation processes. During aerobic wastewater treatment, the C:N:P. ratio should be in the range between 100:10:1 and 100:5:1.
Why is open ocean so low in productivity?
In surface waters away from coastlines, generally there is plenty of sun but not enough nutrients. So most of the ocean surface is not very productive. The water is too deep for storms to stir up nutrients from the bottom and there isn’t upwelling.
What are the 3 main parts of the continental margin?
The continental rise, continental slope, and continental shelf are the three basic components that actually make the entire structure of continental margins. The continental slopes and the continental shelves are structural constituents of continents even though they are below the surface of sea.
Which ocean zone has the highest productivity?
epipelagic
The uppermost zone, from the sea surface to a depth of 200 m (656 ft), is called the epipelagic or photic zone. The large amount of available sunlight makes this the most productive zone of the ocean.
Which ocean zone has the lowest productivity?
Red end of spectrum is highest productivity, blue/violet end is lowest. The overall pattern with latitude is clearly visible: low productivity in the tropics and subtropics, probably due to nutrient limitation brought about by strong, year-round thermocline and pycnocline.
What is the molar ratio?
A molar ratio is between the number of moles (or molecules) of reactants consumed and the number of moles (or molecules) of products generated in a chemical reaction.
Which is the largest reservoir of inorganic carbon in the ocean?
Sedimentary carbonates and kerogen are the the largest carbon reservoirs, followed by marine dissolved inorganic carbon (DIC), soils, surface sediments, and the atmosphere.
What is the range of C N P ratio?
ratio of 10:2:1, corresponding to the average element composition of microorganisms in soil.
Does low C:N ratio means slow decomposition rate?
Lower the ratio and higher will be the decomposition. For examples, plants have high amounts nitrogen content and faster will be the decomposition rate.
