Anewly formed volcanic island can trigger which process in an ocean ecosystem?
a.) primary succession
b.) secondary succession
c.)convergent plate boundary
d.) divergent plate boundary

The answer should be C. Convergent plate boundary is when 2 or more plate tectonics in the lithosphere and move toward one another and collide. Which I believe is when a volcano is in the process of being formed. But if I were you I'd look into Divergent Plate Boundaries as well. 

Where is the rest of the question
