Ecological Succession

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of progressive changes in species composition and community structure.

Front

What is primary succession?

Back

Primary succession is the type of ecological succession that occurs in an area where no soil exists, such as after a volcanic eruption or glacial retreat, starting from bare rock.

Front

What is secondary succession?

Back

Secondary succession is the type of ecological succession that occurs in an area where soil is already present, typically following disturbances like fires, floods, or human activities.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously uninhabited or disturbed environments, playing a crucial role in soil formation and nutrient addition.

Front

Give an example of primary succession.

Back

An example of primary succession is the colonization of bare rock by lichens and mosses after a volcanic eruption.

Front

What is the role of pioneer species in primary succession?

Back

The role of pioneer species in primary succession is to create soil and add nutrients to the environment, facilitating the establishment of other plant species.

Front

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached a steady state through the process of succession.

Front

How does secondary succession differ from primary succession?

Back

Secondary succession differs from primary succession in that it occurs in areas where soil is already present, allowing for faster recovery and re-establishment of the ecosystem.

Front

What factors can trigger secondary succession?

Back

Factors that can trigger secondary succession include natural disturbances like wildfires, hurricanes, and human activities such as farming or logging.

Front

What is the significance of ecological succession?

Back

Ecological succession is significant because it helps ecosystems recover from disturbances, promotes biodiversity, and contributes to the stability and resilience of ecological communities.
