Dependencies
What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.
Foundations · builds on
DecomposerenablesNitrogen cycleEstablished
decomposer enables nitrogen cycle.
Mechanism: Decomposers drive the nitrogen cycle: by breaking down dead matter, they release nitrogen back into the soil for plants to reuse.

Enables · leads to
Eutrophicationemerges fromNitrogen cycleEstablished
eutrophication emerges from the nitrogen cycle.
Mechanism: Excess nitrogen and phosphorus overload the nutrient cycles.

System context
Ammonificationis part ofNitrogen cycleEstablished
ammonification is part of the nitrogen cycle.
Mechanism: Ammonification recycles nitrogen from dead matter.

denitrification is part of the nitrogen cycle.

Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Currently dark in the atlas: no key date stored · 6 of 6 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Builds on 1 foundation (requires / depends-on / derived-from / emerges-from).
structural · Structural graph analysis — not a claim of importance, causation or history.
Exercises 2 annotated mental models — a concept that connects several thinking patterns.
curated · Curated annotations, not a derived measure.
Structural neighbourhood: 6 → 20 → 87 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Its dependency reading rests on 1 foundation relation. structural
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
Dependency radial
What this concept builds on (left) and what it makes possible (right) — derived from dependency and causal relations.
Seen through each discipline
How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.
Through this lens it connects to Carbon cycle and Decomposer.
Through this lens it connects to Decomposer, Nitrification, Denitrification and Eutrophication.

Stocks and flows
A stock is an amount that accumulates; flows are the rates that add to or drain it. The stock changes only when inflow and outflow differ.
Think of a bathtub: the water level (stock) rises or falls depending on the tap (inflow) and the drain (outflow).
Conservation
Some quantity stays constant no matter how a system rearranges — it can move or transform but is never created or destroyed.
Track the conserved quantity like an accountant: whatever leaves here must show up there. A missing amount means you've missed a path.
