Question

which of the following could reset the process of secondary succession? clearcutting or plowing by humans an increase in invasive species excess rainfall

Explanation:

Secondary succession occurs in areas with existing soil (after disturbances like fire, logging). Clearcutting/plowing by humans removes vegetation, resetting secondary succession (as it's a human - caused disturbance that restarts the succession process in a community with soil). Invasive species alter communities but don't “reset” succession. Excess rainfall may cause flooding but isn't a typical reset for secondary succession like human - induced vegetation removal.

Answer:

A. clearcutting or plowing by humans
