Question

when mt. st. helen erupted in 1980, all living organisms within the immediate blast zone were killed by the explosion and debris. what type of succession occurred in this area following this catastrophic disturbance?

Answer 1

Primary succession occurred in this area following this catastrophic disturbance.

When a new piece of land is produced or is first exposed, primary succession occurs. This may occur, for instance, when lava solidifies and forms new rocks or when a glacier recedes and reveals bare rocks. In the initial succession, organisms have to start over.

When fresh land is created or bare rock is exposed, primary succession takes place, creating an environment that can support the first colonization of an ecosystem.

In situations where the soil is unable to support life due to reasons like lava flows, recently formed sand dunes, or boulders left behind by a retreating glacier, primary succession takes place.
