Which of the following is a factor determining where in the intertidal zone a given species will tend to be found?
A. Some parts of the tidal zone are more saline than others because water evaporates from the surface of the ocean and that concentrates salt there. Some species prefer more saline conditions than others.
B. The frequency and duration of wetting: high-intertidal zones are wetted least and low intertidal zones are wetted most, and different species prefer different amounts/frequencies of wetting.
C. The rocks are smoother further down the intertidal zone because of increased weathering from waves, and some species prefer smoother rocks.
D. There is more sand further down the intertidal zone, and some species prefer more sand.
E. The chances of being swallowed by the kraken are greater in the lower parts of the intertidal zone, and some species are more equipped to live with that risk than others.
