Succession

Objectives Chapter 19 Describe the process of succession. Section 2 Ecological Succession Objectives Describe the process of succession. Contrast primary and secondary succession. Explain how mature communities develop.

Chapter 19 Regrowth of a Forest Section 2 Ecological Succession Regrowth of a Forest Succession The replacement of one type of community by another at a single place over a period of time is called succession. The regrowth of a forest after a forest fire is an example of succession. Succession takes place in all communities, not just those affected by disturbances such as forest fires.

Chapter 19 Primary Succession Section 2 Ecological Succession Primary Succession Sometimes, a small community starts to grow in an area where other organisms had not previously lived. Over a very long time, a series of organisms live and die on the rock. The rock is slowly transformed into soil. This process is called primary succession.

Chapter 19 Secondary Succession Section 2 Ecological Succession Secondary Succession Sometimes, a community is disturbed in some way. If soil is left intact, the original community may regrow through a series of stages called secondary succession.

Mature Communities and Biodiversity Chapter 19 Section 2 Ecological Succession Mature Communities and Biodiversity In the early stages of succession, only a few species grow in an area. As a community matures, it may be dominated by a well-adapted, slow-growing climax species. The variety of species that are present in an area is referred to as biodiversity. Having biodiversity helps communities lessen the impact and spread of disturbances such as insect invasions.

Mature Communities and Biodiversity, continued Chapter 19 Section 2 Ecological Succession Mature Communities and Biodiversity, continued Mature communities tend to have biodiversity. A mature community simply has organisms that are well adapted to live together in the same area over time.
