which of the following enviroments 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.

Here is why:
The "A" forest may still have some seeds left over and it will have succession but it would be secondary succession.
"C" says 'any environment' which means that there may already be life there, so it would not be primary succession
"D" already has life, and it is currently going through secondary succession (cornfield --> weeds)
