Transcript 5.3 Notes: Succession

5.3 Bellringer/ How Ecosystems Change
I. Succession-changes that take place
in a community
A. Primary succession-colonization of new sites.
1. New lava or rock from a volcano
2. Sand bar that rises from shifting sand
in the ocean
3. Land slide
4. The 1st organisms in a community are
called pioneer species
B. Secondary Succession-changes take place
after a natural disaster has taken place
or a community has been disrupted by
human actions
1. A community that changes very little
is known as a Climax Community
The Water Cycle
Draw a picture of the water cycle and be sure
to include the following terms:
1. Condensation
2. Precipitation
3. Evaporation
4. Transpiration
5. Runoff
