Process:  - Adult mushrooms produce spores - Release them into the air by process of sporulation - Spores are carried by the wind - Land in a hospitable growing environment - The spores germinate into the soil - The mushroom starts growing - The adult mushroom produce spores of its own to repeat the process.  Perturbation hypothesis: suppose more toxins get eliminated happens, how will it affect MORE or LARGER mushrooms.  Does the supposed perturbation have an effect (direct or indirect) on the process?

no
