The following statements explain the interaction among living and non-living things in an estuary and intertidal zone EXCEPT one.

• The living organisms can be protected in this area by anchoring themselves to the rocks.

• Some organisms like barnacles and mussels can also hold seawater in their closed shells to from drying out during low tide.

• The sediments found in this area are filled with different species of clams

• The living and non-living things in the two ecosystems do not coexist.
