Strong detrital component Dominated by suspension feeders Dominated by macroorganisms Complex predator-prey and competitor interactions The supralittoral zone is roughly above low and below high neap tides. exposed only during the highest high tide exposed only during the lowest low tide. inundated al all times. above the intertidal zone and affected by splash or spray from wave actions. Within a sandy shore environment, the following is incorrect? There is a large detrital component. There are many herbivores. There is high diversity in areas of high moisture.
