which of the following defines when new rock is exposed from a geological or natural disturbance, then erosion degrades the rock over a period of time to make mineral soil, allowing new organisms to populate the area?
ecosystem decay
primary succession
ecosystem development
secondary succession

Explanation:

Primary succession occurs in areas where there was no previous soil, like when new rock is exposed, eroded to form soil, and new organisms colonize. Ecosystem decay is about deterioration, ecosystem development is a broader term not specific to this process, and secondary succession occurs in areas with pre - existing soil.

Primary succession
