Question

When lichens grow on bare rock, they may eventually accumulate enough organic material around them to supply the foothold for later rooted vegetation. These early pioneering lichens can be said to do what for species arriving in a later successional stage?

A. inhibit
B. exclude
C. facilitate
D. tolerate
E. concentrate

Answer 1

The correct answer is C. facilitate.
