Final answer:
Organisms living in the rocky intertidal zone can withstand changes in salinity, water temperature, and the pounding of waves.
Step-by-step explanation:
Organisms living in the rocky intertidal zone are able to withstand changes in salinity, water temperature, and the pounding of waves. The intertidal zone is an extremely variable environment due to tides, with organisms being exposed to air and sunlight at low tide and being underwater during high tide. Additionally, the shore of the intertidal zone is repeatedly struck by waves, requiring the organisms to have adaptations to protect themselves from wave damage.
