A tornado strips out a section of a forest. What type of succession is this? Why?
Archy [21]

Answer:

Secondary succession

Explanation:

A secondary succession is when a type of disturbance happens when there is <em>already </em>soil present. In this case, it has already started out with a forest (including plants, trees, and wildlife). Other examples of a secondary succession include a wildfire, hurricane, flood, or human destruction.

This is different from a <em>primary succession</em>. A primary succession occurs when  there is <em>no</em> soil present.
