Community Structure & Growth Ecological Succession Primary Secondary Describe the changes that occur from left to right in the picture? If the original plot was plowed, is this primary or secondary succession?

Biogeochemical Cycles Consist of same basic structure/parts: Major chemicals Reservoir/storage Assimilation (into organisms) Release (from organisms) For each cycle that follows provide an example of the information above.

Water cycle Major chemicals ….water (duh!) Reservoir/storage Assimilation (into organisms) Release (from organisms)

Water Cycle l

Carbon Cycle Major chemicals Reservoir/storage Assimilation (into organisms) Release (from organisms)

Carbon cycle g

Nitrogen Cycle Major chemicals Reservoir/storage Assimilation (into organisms) Release (from organisms)

Phosphorus Cycle Similar to others but does not have an atmospheric component. See pg for details.

Energy Flow Trophic levels –define and provide examples. Primary Secondary Tertiary/quaternary

Ecological Pyramids Energy-Why is a percentage of energy lost as you ascend the pyramid?

Ecological Pyramids Biomass – Why does the biomass pyramid reflect the same trend as the energy pyramid?

Following the Flow Food chains – Create a simple, but specific example. Food webs - Create a simple example using at least 10 organisms.
