True. Salt is more concentrated in the intertidal zone than in the subtidal, because water evaporates at low tide. However, salt does not accumulate as much as it does in the spray zone.
Concentration of salt varies with tides and evaporation rates. Organisms of the intertidal zone must be able to cope with these fluctuations. Try again.
