Which long-term biome shift results when volcanic ash inhibits pedogenesis?

💡 Explanation

Failure of pedogenesis limits nutrient release into the soil because ash deposition hinders mineral weathering, therefore plant growth declines causing biome aridity rather than a swamp improving because slower nutrient cycling outpaces other geochemical changes.
