Ecological Succession

Front

What is ecological succession?

Back

Ecological succession is the process of change in the species structure of an ecological community over time.

Front

What is primary succession?

Back

Primary succession occurs in lifeless areas where there is no soil, such as after a volcanic eruption.

Front

What is secondary succession?

Back

Secondary succession occurs in areas where a disturbance has destroyed an existing community but left the soil intact, such as after a forest fire.

Front

What is a microhabitat?

Back

A microhabitat is a small, specific habitat within a larger ecosystem that provides unique conditions for organisms.

Front

What role do pioneer species play in succession?

Back

Pioneer species are the first organisms to colonize barren environments, initiating the process of ecological succession.

Front

What is the difference between primary and secondary succession?

Back

Primary succession starts with bare rock and no soil, while secondary succession begins in areas where soil is already present.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of different species.

Front

What are climax communities?

Back

Climax communities are stable, mature ecosystems that have reached a steady state through the process of succession.

Front

What is a disturbance in an ecosystem?

Back

A disturbance is an event that significantly alters the structure of an ecosystem, such as a hurricane, fire, or human activity.

Front

How does soil formation occur during primary succession?

Back

Soil formation during primary succession occurs as weathering of rock and the accumulation of organic matter from pioneer species.
