Transcript of Ecological Succession
First new plant species to begin growth
Do not need soil to survive
Examples: lichens, beach grass
What am I?
Slow, gradual replacement of a community
Begins with bare rock
(NO soil present!!!)
Starts with the arrival of a pioneer community
Pioneer organisms of primary succession
Collect water and nutrients from the air (so they don't need soil to grow!)
Steady replacement of a previous community
Begins where soil remains
No need for pioneer species
Much faster rate than primary succession
Examples: Forest Fire
(man made or natural)
Can you think of any other disturbances that could start secondary succession?
Secondary Succession Stages
break down the rocks into smaller pieces
As lichens die, they decompose, adding small amounts of organic matter to the rock to make soil
Simple plants like
mosses and ferns
can grow in the new soil
The simple plants die, adding more organic material and nutrients
The soil layer thickens, then
grasses, wildflowers, and other plants
begin to take over
Succession continues on.....
These plants dies and decompose and add more nutrients to the soil
Shrubs and small trees
can now survive
A mature, diverse group of plants and animals colonizing an area
Stable climax communities are the final end result of the succession process
(variety of species)
Insects, birds, and mammals finally begin to move in
What was once bare rock now supports a variety of life!
What DOES the fox say???
Hardwood trees like oaks, maples, and birch
Cacti in deserts
Tall grasses in prairies
Can you guess what these pictures are?
Sandstone erosion in Nevada
Tornado destroying a house
Moss and Lichen on tree bark
ECOLOGICAL SUCCESSION WINDOWPANE NOTES
A series of changes in a community where new populations replace previously existing ones
Causes: natural or human disturbances
Increase in biomass
