(a) ________________________ are constantly changing. Both (b) ________________________ and biotic factors change in every ecosystem. One type of ecosystem change is called (c) ______________________. This results in one community replacing another over time. This process might begin on bare rock formed from the cooling of molten (d) __________________. This process begins when (e) ________________ & (f) ________________, also known as the (g) _________________________________________, begin living on and breaking down bare rock. When these organisms die, their remains mix with the rock pieces to form a thin layer of (h) __________________________. This process of establishing and developing an ecosystem in a previously uninhabited area is called (i) ________________________________. The mature community that eventually forms is called the (j) ________________________________________. Sometimes that community is destroyed by a (k) ___________________________. A new community will replace the destroyed one through the process of (l) ______________________________________. This process happens much (m) __________________ because the soil is usually left (n) __________________.
