A remote island ecosystem experiences a volcanic eruption that eliminates all vegetation and animal life. Which process explains the subsequent, predictable recolonization of the island by various species?

A)Random species mutation dominates
B)Convergent evolutionary adaptation
C)Ecological primary succession occurs
D)Competitive exclusion predominates always

💡 Explanation

Ecological primary succession explains recolonization because pioneer species colonize barren environments, modifying them to allow other species to establish; therefore, succession explains the progression, rather than random mutation or competitive exclusion determining which species appear first.
