Me asap n o guess after a volcanic eruption, lava flowed over an area and then cooled to form a thick layer of new rock. one thousand years later, a thriving forest with diverse flora and fauna is found in that area, even though evidence suggests that several large forest fires have occurred. which statement best describes what happened? secondary succession occurred, followed by several primary successions. only secondary successions occurred. primary succession occurred, followed by several secondary successions. only primary successions occurred.

Secondary succession occurred, followed by several primary successions.

Explanation:

Starting of life at an area where there was no previous life, is called primary succession. After volcanic eruption, cooled lava formed a thick layer of new rock. Primary succession can occur on the newly formed rock. The first species or the pioneer species such as lichen, moss begins to grow in the new rock. Once these pioneer species get established, the habitat is changed and secondary succession will begin with the growth of more complex flora. Thousand years later, a forest with diverse flora and fauna is found in that area.
