Which of the following statements is true of a rocky shore ecosystem? select all that apply. a animals in the middle and low tide zones can only feed during high low tide. b filter feeders are common. c deposit feeders are rare. d tide pools remain submerged during low tide.

The correct answer is option A, B, C

Filter-feeders like barnacles, mussels, oysters, tubeworms, limpets, chitons, snails, crabs and starfish are invertebrates found on the rocky shore  

Animals and plants live on rocky shores in the intertidal zone which is the area between high and low tide and thus these organisms are able to cope up with two environmental conditions.  They are exposed to extremes of temperature and salinity, and flooded by sea water. They are also exposed to drying air twice every 24 hours. They save themselves by birds, molluscs and crabs during low tide and by fish and other marine life during high tide.

A Deposit Feeder is an aquatic animal that settles at the bottom of the ocean and feed on organic matter thus is very rare in rocky seashore.
