Explanation:

Primary succession starts on entirely barren, lifeless substrates (like bare rock) with no existing soil, so it takes a very long time to establish a stable ecosystem. Secondary succession occurs in areas where an existing ecosystem was disturbed (like a forest fire or abandoned farmland) but soil and some biological remnants (seeds, roots) remain, allowing the ecosystem to regenerate much faster. Option B is incorrect because secondary succession is faster, not slower. Option C is wrong as both types of succession can occur in various habitats, not restricted to mountains or wetlands. Option D is incorrect because both primary and secondary succession involve changes in both plant and animal species over time.

Answer:

A) Secondary succession is typically quicker than primary succession
