Succession

Front

What is primary succession?

Back

Primary succession is the process of ecological change that occurs in an area where no soil exists, starting from bare rock, often initiated by pioneer species like lichen.

Front

What is secondary succession?

Back

Secondary succession is the process of ecological change that occurs in an area where soil is already present, typically following a disturbance such as a fire or flood.

Front

What is a climax community?

Back

A climax community is a stable ecological community that has reached equilibrium, where species composition remains relatively unchanged until a disturbance occurs.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously uninhabited or disturbed environments, such as lichen and moss in primary succession.

Front

What is ecological succession?

Back

Ecological succession is the gradual process of change and replacement in the species composition of a community over time.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs on bare rock without soil, while secondary succession occurs in areas where soil is already present after a disturbance.

Front

What role do disturbances play in succession?

Back

Disturbances, such as fires or floods, can reset ecological succession, allowing secondary succession to occur and leading to new community dynamics.

Front

Can both types of succession lead to a climax community?

Back

Yes, both primary and secondary succession can eventually lead to a climax community, although the time frames and processes may differ.

Front

What is an example of primary succession?

Back

An example of primary succession is the colonization of bare rock after a volcanic eruption, where lichen and moss are the first to grow.

Front

What is an example of secondary succession?

Back

An example of secondary succession is the regrowth of a forest after a wildfire, where soil and some plant life remain.
