Front

What happens during the first stage of primary succession?

Back

During the first stage of primary succession, pioneer species such as lichens and mosses colonize bare rock and begin to create soil.

Front

What role do pioneer species play in succession?

Back

Pioneer species are the first organisms to colonize a barren environment, helping to create soil and conditions suitable 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 and some organisms still exist after a disturbance.

What is an example of secondary succession?

Back

Abandoned railroad tracks overgrown with weeds, followed by the growth of small aspen trees after ten years.
