Tell if grass poking through a crack in a sidewalk is an example of primary or secondary succession? explain

Biology

This would be an example of secondary succession because there was once an ecosystem. In addition, if there wasn't an ecosystem that would mean that the sidewalk was there before the growth of plants. However, that would not be possible because concrete wasn't made before the growth of plants.

Secondary due to the fact that there was an ecosystem already there before the sidewalk was built over it
