Primes¶
- Reservoir-Flux Network
- The nitrogen, phosphorus, water, and sulfur cycles share the shape.
This sourceStandard reference presenting the carbon, nitrogen, phosphorus, sulfur, and water cycles as reservoir-and-flux systems with conservation closure.
- The nitrogen, phosphorus, water, and sulfur cycles share the shape.
- Rock Cycle
- Biogeochemical cycles. The water cycle (vapor, cloud, precipitation, surface water, groundwater, ocean), the carbon cycle (atmospheric CO₂, biomass, soil and sediment, fossil fuel), and the nitrogen, phosphorus, and sulfur cycles — a small set of phases, named transformations, identity preserved across them.
This sourceComprehensive reference on the carbon, water, nitrogen, phosphorus, and sulfur cycles, reservoirs, fluxes, and residence times.

Domain-specific¶
- Biogeochemical Cycling
- Carbon spends roughly five years in the atmosphere as CO₂, roughly a thousand years in deep ocean water as dissolved inorganic carbon, and up to hundreds of millions of years locked in carbonate rock
This sourceThe standard graduate biogeochemistry text, cited for the reservoir stocks and residence times of carbon across atmosphere, deep ocean and carbonate rock; the specific figures in this sentence were not checked against its text at review.
- Carbon spends roughly five years in the atmosphere as CO₂, roughly a thousand years in deep ocean water as dissolved inorganic carbon, and up to hundreds of millions of years locked in carbonate rock
- Nitrogen Cycle
- Nitrogen fixation converts inert N₂ to reactive ammonia, performed by free-living bacteria (Azotobacter, Cyanobacteria) and symbiotic associations (Rhizobium in legume root nodules, Frankia in alder and other actinorhizal plants); this step is the rate-limiting input to most biological systems because breaking the N≡N triple bond requires the nitrogenase enzyme complex under anaerobic conditions and is energetically expensive

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Read against the text for 1 of 4 citations: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
