Lasting close association establishes no mutual benefit, and continued coexistence establishes no exchange. Competition needs a specified limiting resource; an indirect inference needs support for each link. Human rules require grounds of their own.
Questions explored
Is symbiosis necessarily mutually beneficial?
Not in the explicit broad Biology 2e framework: lasting close association and participants’ outcomes are different questions.
Does coexistence establish mutual help?
No. In Tilman’s selected finding the species persisted with different resource limitations; exchange requires separate evidence.
Why are plants and fungi described as rewarding partners?
This expresses reported resource-transfer dependencies in Kiers’s abstract; conscious intention and moral superiority are not established.
Can nature prescribe unlimited help or cruelty to a person?
That step adds a human rule. Its grounds and limits require discussion separate from the biological description.
Key distinctions
Darwin uses struggle for existence broadly, including dependencies and leaving offspring. (Darwin 1859, Chapter III, 502–505)
Biology 2e uses a broad definition of symbiosis and distinguishes effects on participants. (Biology 2e, 45.6, 73, 75–77, 80–82, 87–89)
In Tilman’s selected abstract, dominance and coexistence vary with the limiting resource. (Tilman 1977, complete publisher abstract 67–68)
Kiers and colleagues report conditional bidirectional resource transfers in studied mycorrhizal exchange. (Kiers and colleagues 2011, complete abstract 238–239)
The notebook, arrows, and neighbours are invented; distinguishing relations from human prescriptions is an author application. (United Wisdom, invented teaching notebook)
Limits of interpretation
- Do not merge broad close association with mutual benefit.
- Do not reduce Darwin, Chapter III, 502–505 to direct armed conflict.
- Make no Tilman coexistence proof of exchange or every community’s laws.
- Extend no Kiers 2011 abstract 238–239 to every network, conscious contracts, or moral rank.
- Do not present Darwin, Chapter III, 558–562 as a complete current independently confirmed field measurement.
- Bind no invented diagram or author exercise to a primary source as its validation.
- Derive no human cruelty, unlimited-help obligation, or exercise efficacy from an ecological description.
