Answer:
There is less biodiversity in the ecosystem.
Explanation:
Since the barren ground doesn't provide suitable living conditions for most of the living organisms, the ones that need the lest resources to survive create the primary succession, usually the mosses and lichens. The organisms of the primary succession provide biomass, so the ground is mixing with it, thus new soil is forming.
Comparative and experimental investigations are two of three scientific investigations, the other is descriptive investigations.
