15. Which of the following environments is the most likely candidate for primary succession?

Question

A. A forest reduced to ash by an intense fire

B. A newly formed volcanic island

C. Any environment that can be reached by wind-blown seeds that cross oceans

D. A weed-ridden, abandoned corn field

Answer 1

B - primary succession occurs when there is absolutely nothing there to start.  Even in a forest that is reduced to ash, there is a latent seed-cache in the soil.  This cache has actually been waiting for a fire to come along - most of those seeds require fire to germinate.  

On a newly formed volcanic island, there's nothing - not even sand - there to start out.
