(1) Ecosystems are constantly changing. Both (2)abiotic factors and
biotic factors change in every ecosystem. One type of ecosystem
change is called (3) succession. This results in one community replacing

the cooling of molten (4) lava. This process begins when (5) moss & (6)
lichen, also known as the (7)pioneer species, begin living on and (8)
break-down bare rock. When these organisms die, their remains (9) mix
with the rock pieces to form a thin layer of (10) soil. This process of
establishing and developing an ecosystem in a previously uninhabited
area is called (11) primary succession. The mature community that
eventually forms is called the (12) climax community. Sometimes that
community is destroyed by a (13) natural disaster. A new community
will replace the destroyed one through the process of (14) secondary
succession. This process happens much (15) quicker because the soil
usually (16) remains.
