A. The rotting remains of plants add to the fertility of the soil.
B. The soil becomes so fertile that eel grass is replaced by other plant species.
C. The roots from plants help stabilize the sediment, keeping it in place.
D. The concentration of salt becomes so high that all plant life is destroyed.
