Succession
After a natural disaster occurs in a healthy ecosystem, secondary succession will cause the ecosystem to return to its original _________.
Climax community.
When a disturbance changes a community without removing the soil, what type of succession follows?
Secondary succession.
During primary succession, __________ plays a large role in determining which pioneer species arrives in an area first.
Surrounded areas
Why does secondary succession typically proceed faster than primary succession?
Because it mostly occurs on a surface where an ecosystem has previously existed. Primary succession only occurs on a surface where no ecosystem existed before.
Primary Succession
Begins in areas with no remnants of an older community. It occurs on bare rock surfaces where no soil exists. Often produces the original climax community. Starts in area of burnt areas or burnt forest. Also starts in places like sand dunes.
The clearing of a rain forest is the example a(n) ________ drastic enough to prevent the original climax community from reforming.
Human caused disturbance
What are two kinds of disturbances that change ecosystems?
Natural disasters and hurricanes
What is the development of a climax community?
Natural fires
Secondary succesion
Occurs when a disturbance changes a community without completely destroying it. Usually occurs in an old field and has much more diversity.Often produces the original climax community.
Pioneer species
The first species to live in an area of primary succession.
Describe the process of Succesion in an ecosystem.
The number of different species usually increases. The series of plants and animals changing overtime.
Ecological Succession
The series of predictable changes that occurs in a community over time.
What does both Primary Succession and Secondary Succession both have in common?
They are both an extended process; Both abiotic factors, both start out w/ pioneer species. Both in an climax community.
