  1. A.Interspecific competition
  2. B.Mutualism
  3. C.Brood parasitism
  4. D.Commensalism
Show answer
Correct answer: A. Interspecific competition

Connell showed in the field that on the intertidal rocks of the Scottish coast the larger and faster-growing barnacle Balanus physically crowds out the smaller Chathamalus wherever the two settle together, so that Chathamalus survives only higher up the shore where Balanus cannot tolerate the exposure.
