Ecological Succession - Summary An example of succession.

Ecological succession 2

See Article History Alternative Titles: Two different types of succession—primary and secondary—have been distinguished. Primary succession occurs in essentially lifeless areas—regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunesor rocks left from a retreating glacier.

Secondary succession occurs in areas where a community that previously existed has been removed; it is typified by smaller-scale disturbances that do not eliminate all life and nutrients from the environment. Here, a sunken ship demonstrates the process in a tropical coral reef.

Ecological succession is the process that describes how the structure of a biological community that is, an interacting group of various species in a desertforestgrasslandmarine environmentand so on changes over time.

Species that arrive first in a newly created environment such as an island rising out of the sea are called pioneer species, and they, through their interactions with one another, build a rather simple initial biological community.

The structure of this community becomes more complex as new species arrive on the scene. At every stage there are certain species that have evolved life histories to exploit the particular conditions of the community.

This situation imposes a partially predictable sequence of change in the physical environment and species composition of communities. What is primary succession? Primary succession is ecological succession that begins in essentially lifeless areas, such as regions in which there is no soil or where the soil is incapable of sustaining life because of recent lava flows, newly formed sand dunesor rocks left from a retreating glacier.

These plants also provide habitats for small animals and other forms of life. These plants are replaced by grasses and shrubswhich shade out the first colonizers and alter the soil further, before large trees and more shade-tolerant species replace the community of sun-loving grasses and shrubs.

Each community may support different collections of animal species.Succession is a series of progressive changes in the composition of an ecological community over time.

Community structure & diversity

In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. Notes #2- NAME_____ Ecological Succession. Period_____ Date_____ Answer the following: _____-all of the different organisms that live together in an area.

What is Ecological Succession? Ecological succession is the term used to describe what happens to an ecological community over time. It refers to more or less predictable and orderly set of changes that happen in the composition or structure of ecological community.

Ecological succession: Ecological succession, the process by which the structure of a biological community evolves over time. Ecological succession is the observed changes in an ecological community over time.

The community develops in a new area that may not have been colonized previously or one that was previously. Ecological succession, a fundamental concept in ecology, refers to more-or-less predictable and orderly changes in the composition or structure of an ecological community.
