Flashcards
0/8
Facilitation
A process in succession where earlier species change the environment, making it more suitable for successive species to survive.
Pioneer Species
The first organisms to colonize a barren environment in primary succession; they modify the environment, making it more suitable for subsequent species.
Primary Succession
The development of an ecosystem in an area that has never previously supported a community and lacks soil. Typical of areas like bare rock exposed by a retreating glacier.
Climax Community
A stable, mature community in the final stage of ecological succession, which can reproduce and sustain itself. This community is in equilibrium with the environment and changes are slow.
Secondary Succession
The sequential reappearance of a community after a disturbance (such as a fire, flood, or human activity) destroys an existing ecosystem but leaves the soil intact.
Disturbance
An event that disrupts ecosystem, community, or population structures and changes resources, substrate availability, or the physical environment.
Seral Community
An intermediate stage found in ecological succession in an ecosystem advancing towards its climax community. Also known as a seral stage.
Intermediate Succession
Stages between pioneer and climax communities where species replacement occurs as the habitat improves and supports a wider diversity of life.
