Compare the sandy intertidal and rocky intertidal with respect to the types of feeding exhibited by ...

Since the rocky intertidal is so wave swept, and since the substrate is hard and does not absorb food particles, deposited materials tend to get washed away with the receding tides and waves. As a result, deposit feeding is uncommon in the rocky intertidal, with the possible exception of tide pools. Sandy beaches, on the other hand, have larger accumulations of deposited material that is retained by the soft sediments in these areas. Deposit feeders are more common here than in rocky areas. In both rocky and sandy intertidal areas, filter feeding is prevalent due to the abundance of water-born food particles. Scavenging and predation are also common in these two areas.
