During Secondary Succession, Detritivores and Decomposers Are Often Among the Most

During secondary succession, detritivores and decomposers are often among the most important early colonizers.What do these species do to initiate and advance succession?

A) They are facilitators that release nutrients and improve soil for the first colonizing plants.
B) They are facilitators that enable the immediate colonization of large, perennial plants such as trees.
C) They are inhibitors that prevent the emergence of "weedy" plants, thus preventing them from competing with plants more adapted to the environment.
D) They are inhibitors that cause the rapid death and breakdown of early colonizers, allowing later colonizers to become established more quickly.
E) They are both facilitators and inhibitors, facilitating the colonization of plants adapted to that environment and inhibiting those less adapted.
