What are some stresses that affect the organisms residing in the intertidal zone?

6 Biotic factors affecting organisms living in the intertidal zone:
Competition for space and food Predation Reproduction Substrate settlement preference Osmoregulation (dessication)

7 Abiotic factors affecting organisms living in the intertidal zone:
Salinity Temperature Air and light exposure Tidal flow Waves and current action Substrate Wind direction and strength Dissolved O2 Storms Natural Disasters

8 What are some adaptations to living in the intertidal zone?
