Common mistakes in Sorting interactions by who gains and who loses
Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.
- Confusing predation with competition because both can reduce the fitness of one participant.
- Concludes that predators eliminate prey, which is the opposite of the lesson.
- Swaps camouflage and chemical distastefulness between the examples.
- Reads exclusion from a zone as partitioning of it.
- Treats the observation as a refutation of Gause rather than as partitioning.
- Assumes competition needs related species, or reclassifies grazing as predation.
