A new island formed by volcanic action may eventually become populated with biotic communities. describe the type of ecological
Katyanochek1 [597]

The type of ecological succession being described in the illustration is primary succession.

<h3>What is primary succession?</h3>

It is a form of succession that occurs when an area that has never been occupied by any living organism becomes exposed and eventually gets colonized by living organisms.

It is quite different from secondary succession which happens when an area that has been housing biotic communities before gets disrupted by a major disturbance.

A new island formed by volcanic action has never housed any biotic community before. Thus, only primary succession can occur there.
