Lesson 7: Succession
* school science ecology1. Definition
Succession is the gradual and usually predictable changes in the composition of a community and the abiotic conditions following a disturbance. It describes how ecosystems change over time to support life and become more stable and biodiverse. It allows for ecossystems to recover after natural disasters or Ecological Disturbances.
1.1. Primary Succession
Primary succession is from an area where no life previously existed. Organisms that can survive at the beginning of primary succession are called pioneer organisms
1.2. Secondary Succession

:END: Secondary succession occurs when ecosystems have already started to develop, but they experience a Ecological Disturbances. A change happens that impacts some of the organisms in that ecosystem.
1.3. Aquatic Succession
Pond fill with organic matter. This allows plants that contribute to organic matter in the pond to grow, resulting in smaller and shallower ponds over time. Finally, the pond completely fills up with sediment and organic matter resulting in solid ground.
2. Benefits
Succession allows for the recovery of ecosystems and offers hope that environmental damage can be reversed. Succession increases Biodiversity and allows for formation of natural ecosystems.
3. The Fluctuation Of Ecosystems.
Ecosystems gradually change over time and adapt to changing environments.
