An estuary collects sediments from the ocean and rivers that feed into it. The sediments swirl around and then settle to form a mudflat. Eel grass is then established on the mudflat. The ecosystem changes over time and ultimately develops into a salt marsh that contains mangrove trees. Which of the following is likely NOT involved in this example of ecological succession?

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.

Can y'all included detail answers on why the other answers are incorrect
