Primary Succession
On this surface, primary succession begins
bare rock
Fire causes some of this tree seed released that normally will not
pine
This type of succession begins as a result of wildfire
Secondary
This planet is known for healing itself from catastrophic events through the process of succession
Earth
This type of weathering might include a tree root splitting a rock.
Biological
These two types of weathering contribute significantly to primary succession
chemical and biological
This important factor present initially in this succession, different from primary
soil
Presidents: Bush Sr., Clinton, Bush Jr., Obama, Trump. This order also represents a general term.
Succession
Defined as the study of the interactions of biotic and abiotic features in ecosystems.
Environmental Science
A biome that has permafrost for most of the year.
Tundra
These two are pioneers to the primary process X 2
lichens and mosses
This is deposited in the soil as a result of dying and decaying organisms
organic matter
A bulldozer completely cleans 5 acres of all plants. _______________ succession will occur next.
Secondary
A term that describes the community interaction of biotic factors with abiotic factors.
ecosystem
As water slows at the mouth of a river, sediment makes this a lush area where fresh and salt water mix. X 2
Estuary
Timeframe for the completion of primary succession
100s of years
Lupens are legumes and advance succession because of their ability to do this X 2
nitrogen fixation
Worms, Birds, Squirrels, Deer, Bear, Large trees, many plants are now present
Mature community
Occurs in areas where a community that previously existed has been removed; either by natural disaster or by man. X 2
Secondary Succession
Area of fertile soil, produces food, but not enough rainfall to support forests. X 3
Grassland
This term describes the presence of various organism types after succession
ecological diversity
These are pioneer species after wildfires
moss
This is organic factor is present in in the initial stage of secondary, but not primary X 2
soil
Two main reasons bare rock is exposed to begin primary succession. X 2
Volcanic lava and Glacial retreat
Zebras, lions, and giraffes occupy this grassland biome.
Savannah
This diverse community is a result of succession being complete
climax
This is a common catastrophic event that allows this type of succession to occur
Wildfire
This diversity is the end result of both types of succession
mature community
Only through this abiotic factor, both primary and secondary succession can occur.
The Sun X 3
This biome is known for trees that shed their leaves annually.
Deciduous forest
