Question

Quizplus · Accepted Answer

The low-water portion of the rocky intertidal zone is the area that is only exposed to the air during low tide, and as a result, it is constantly being hit by waves. This makes it difficult for animals to survive in this area, and they are usually replaced by seaweeds and surf grasses that are adapted to these conditions. Therefore, the best choice is E, seaweeds and surf grasses. The other choices, hermit crabs, fiddler crabs, limpets, and mussels, are found in other areas of the rocky intertidal zone, including the mid to high-water portion.
