A gradual development of a community over time. Often a series of stages is observed during succession
does succession take place in all communities?
a small community that starts to grow in an area where other organisms had not previously lived. There is no soil , usually just bare rock. Over a long period of time a series of organisms live and die on the rock and the rock slowly transforms into soil
takes place in an area where an earlier community was disturbed. There is soil. For example, if a farmer would stop growing crops in an area that had been cleared. If the soil is left intact the original community may regrow through series of stages
How does succession occur?
the formation of new land(cooling of lava, breakdown of rock by lichens, melting of glaciers to expose land) or after a natural and human disturbance
the first organism to start a process of succession
the types of organisms that are usually the pioneer species in primary succession
over time the remains of what add to the soil
insects and other tiny organisms
what process occurs in an area where bare rock is transformed into soil
how long does it take for an area of bare rock to become a forest
hundreds of thousands of years
what is usually the first plant to grow in secondary succession
In secondary succession how long does it take for a forest to form
what is a climax species
A slow growing species that is well adapted to an area over time
what are organisms that live in a mature community able to do
a mature community has organisms that are well adapted to live together in the same area over time
Why is biodiversity important to communities of organisms
a forest that has a high degree of biodiversity is less likely to be destroyed by an invasion of insects. Most plant-damaging insects prefer to attack only one species of plants. The presence of a variety of plants will lessen the impact and spread of invading insects
