Anewly formed island in the middle of the pacific ocean undergoes a series of changes that eventually produces a rainforest community. this is an example of
a. primary succession
b. speciation
c. secondary succession (incorrect)
d. evolution

Primary succession is the series of community changes which occur on an entirely new habitat which has never been colonized before. Examples of such habitats include...volcanic lava and debris, elevated sand banks and dunes, quarried rock faces.

When the tops of the volcanoes appear above the water, an island is formed. Primary succession are changes that appear on the early stages of islands, therefore, the answer is A. Primary Succession.

Hope this helps!
