What is the assumption of Clements in colonizing successional  species?

#Unit 10. Ecological Principles
  1. possession of space is all-important and that the colonists that get there first determine subsequent community structure, such as facilitation
  2. Early colonists may exclude subsequent colonists such as
  3. Any species can start the succession, but the eventual climax community is reached in a somewhat orderly fashion, such as tolerance
  4. Each colonizing species made the environment a little different, such as facilitation

You observed the two species of barnacles, species 1 and species 2, occupy upper and lower strata of intertidal rocks, respectively. Only when species 1 was removed by you from the upper strata, species 2 could occupy both the upper and lower strata. From the choice given below what would be your inference from these observations.
