spread by _______________, _______________, and _______________
currents.
3. The maintenance of a self-sustaining ecosystem requires ___________
___________________________________________________________.
4. Exotic species of organisms have been accidentally introduced into wellestablished native fresh water ecosystem in recent years and have
undergone explosive growth. What is a possible reason for such a
population explosion?
5. After a volcanic eruption has covered an area with lava, what is the most
likely succession in the repopulation of an area?
6. Scientist found that over a period of 200 years a mountain pond was
