Lichens are composed of two organisms, a fungus
that cannot make its own food and algae that contain
chlorophyll. Lichens may live on the bark of trees or
even on bare rock. They secrete acids that tend to
break up the rock they live on, helping to produce
soil. As soil accumulates from the broken rock and
dead lichens, other organisms, such as plants, may
begin to grow.
3. The ability of lichens to alter their environment,
enabling other organisms to grow and take their
places in that environment, is one step in the process
of
A) biological evolution
B) ecological succession
C) maintenance of cellular communication
D) differentiation in complex organisms
