1. Succession: The orderly changes of plant life (producers) in an area. http://www.physicalgeography.net/fundame ntals/images/succession.gif

2. The type of plants determine the order of primary consumers. (herbivores) www.clermont.inra.fr/ urh/eng/eq_acs.htm

3.  The primary consumers determine the order of secondary consumers. http://www.oforest.on.ca/boreal/Plant%20and%20Animal% 20Images20Images/Secondary_Consumers.gif

4. Pioneers are the first of something in an area. The 1st plants in a field are called “pioneer”. Pioneer plants in an area are generally grasses. http://giswetlands.ifas.ufl.edu/photos/BCM/Pi oneer%http://giswetlands.ifas.ufl.edu/photos/BCM/Pi oneer%20plants%20during%20drought%20 on%20trail.jpg

5.  Grasses die and decompose adding to the dirt layer.  Herbs and flowering plants enter. They grow taller than the grass. http://www.nuc.berkeley.edu/students/ asztalos/buttercup.jpeg

6.  Herbs and flowering plants will be killed off.  Next comes bushes and shrubs. http://led.tamu.edu/photogallery/Projects /native%20shrubs.jpg

7.  Next comes softwood trees. These are quick growing trees. An example would be the poplar tree.

8.  Then comes in the conifer or evergreen tree. http://www.cg.tuwien.ac.at/research/rendering/ csg-graphs/Pics/conifer2_1.JPG

9.  Climax species - This is the final phase in succession. A climax species will be hardwood trees such as oak or maple. http://home.comcast.net/~randy.wells/images/o ak_tree_in_back_yard_morning_1.jpg

10.  SECONDARY SUCCESSION occurs when something causes the order to back up : http://discover.edventures.com/images/term lib/s/secondary_succession/support.gif

11.  National : fire, hurricane, tornado, comet impact, volcano eruption, tsunami, earthquake, ice age/glacier, floods http://www.beaglesunlimited.com/desktopimages /western_US_forestfire_and_elk.jpg

12.  Humans: deforestation, urbanization, farming, http://universe-review.ca/I10-81-deforestation.jpg
