Succession and Extinction — Quiz

Question 10 • Biology

Which is one event that may lead to Primary succession?

Answer
A
volcanic eruption
B
introduced species
C
clear-cutting
D
climate change

Explanation

Primary succession begins where there is no soil, such as on newly exposed rock. A volcanic eruption can cover land with lava, which cools into bare rock and may later be colonized by pioneer species. Clear-cutting usually leaves soil behind, so it is more likely to lead to secondary succession.
