- 3. the somewhat predictable series of changes in a community that follows a disturbance (e.g, a fire, logging, or farming) that dramatically alters the community but does not destroy all vegetation or soil life
- 4. The final stage of succession; a stable community that remains relatively unchanged.
- 9. A non-native species that spreads widely in a community
- 10. The somewhat predictable series of changes in a community that follows a disturbance so severe that no vegetation or soil life remainsSecondary Succession

- 2. The number and variety of ecosystems within a particular area
- 5. Tells a scientist how many species exist in a certain environment
- 6. A diagram that shows an area's average temperature and precipitation
