Question

heavy rainfall in a mountainous region caused a landslide that removed all the soil and organisms that inhabit the area. which of the following best describes the type of succession? this is primary succession because it is occurring in an area with bare rock. this is secondary succession because the climax community can start growing. this is primary succession because it would take a very long time for new organisms to move in. this is secondary succession because it occurred in an established ecosystem.

Explanation:

Primary succession occurs in an area with no previous soil or organisms, like bare rock. Secondary succession occurs in an area where a previously - established ecosystem has been disturbed. A landslide removing soil and organisms from a mountainous region is a disturbance to a pre - existing ecosystem. So, this is secondary succession.

Answer:

The last option "This is secondary succession because it occurred in an established ecosystem."
