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.

#Unit 10. Ecological Principles
  1. Upper strata of intertidal rocks is the realized niche of the species1
  2. Lower strata of intertidal rocks is the fundamental niche of the species1
  3. Lower strata of intertidal rocks is the realized niche of the species 2

  4. Both lower and upper strata of intertidal rocks is the fundamental niche of the species1
