Succession

Front

What is primary succession?

Back

Primary succession is the process of ecological change that occurs in an area where no soil exists, such as after a volcanic eruption or glacier retreat.

Front

What is secondary succession?

Back

Secondary succession is the process of ecological change that occurs in an area where soil is present but has been disturbed, such as after a forest fire or human activity.

Front

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached a steady state, experiencing minimal changes over time.

Front

What role do pioneer species play in primary succession?

Back

Pioneer species are the first organisms to colonize barren environments, helping to create soil and establish conditions for other species to thrive.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs in lifeless areas without soil, while secondary succession occurs in areas where soil is already present but has been disturbed.

Front

What is an example of a catastrophic event that can lead to primary succession?

Back

A volcanic eruption is an example of a catastrophic event that can lead to primary succession by creating new land from lava.

Front

How does glacier retreat contribute to primary succession?

Back

Glacier retreat exposes bare rock, creating a new environment for primary succession to occur as organisms begin to colonize the area.

Front

What is the significance of soil in succession?

Back

Soil is crucial for secondary succession as it provides nutrients and a habitat for plants and animals, allowing ecosystems to recover after disturbances.

Front

What are some common pioneer species in primary succession?

Back

Common pioneer species include lichens, mosses, and certain types of grasses that can survive in harsh conditions.

Front

How does biodiversity change during succession?

Back

Biodiversity typically increases during succession as more species colonize the area and establish complex interactions.
