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
Producer (autotroph)depends onPhotosynthesisEstablished
Producers depend on photosynthesis.
Mechanism: Producers make their own food by photosynthesis, which is why they can start a food chain.
Enables · leads to
Food chaindepends onProducer (autotroph)Established
A food chain depends on producers.
Mechanism: Producers capture the energy that then flows to every consumer along the chain.
System context
Producer (autotroph)is part ofEcosystemEstablished
Producer (autotroph) is part of ecosystem.
Mechanism: Producers are the base of an ecosystem: plants and algae capture sunlight to make food, feeding every other organism above them.

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 · 3 of 3 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.
Structural neighbourhood: 3 → 52 → 153 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.
All 3 of its relationships stay within its own discipline — a field-specific concept in the current atlas.
structural · Structural graph analysis — not a claim of importance, causation or history.

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.
What builds on this
1 concept build on this directly, 1 in total, across 1 discipline.
Structural downstream reach along dependency edges — not a claim of historical necessity.
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 Ecosystem, Photosynthesis and Food chain.
What it looks like
Concrete cases that make this idea recognisable in the real world.
Why every food chain starts with a plant
In a meadow, only the grass and wildflowers can make food from sunlight. Every animal there — insects, mice, hawks — depends on that captured energy, which is why producers sit at the base.

Curriculum alignment

Appears in official curriculum objectives
Understand that materials and energy carriers largely move through closed cycles in ecological systems, and that human activity can alter these cycles. · 1.–4. Klasse (zentrales fachliches Konzept)
Exact wording: „Lebewesen sind an Stoff- und Energieumwandlung gebunden. Organische Verbindungen werden vorwiegend von Pflanzen aufgebaut. In ökologischen Systemen durchlaufen Baustoffe und Energieträger vorwiegend geschlossene Kreisläufe. Menschliche Aktivitäten können solche Kreisläufe verändern.“

Pilot slice: mapped to selected official objectives, not a coverage claim. Concept identity is canonical and never redefined by a curriculum.
Producers, like green plants, make their own food through photosynthesis. Because they capture energy first, they are the base that feeds everything else in a food chain.
