Question

A geologist visits an environment to make observations. The scientist predicts that the environment will undergo secondary succession.

What did the geologist likely observe in the environment to draw this conclusion? Check all that apply

Answer 1

Answer:

Secondary Succession

Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. Examples include areas which have been cleared of existing vegetation (such as after tree-felling in a woodland) and destructive events such as fires.

Secondary succession is usually much quicker than primary succession for the following reasons:

1-  There is already an existing seed bank of suitable plants in the soil.

2-  Root systems undisturbed in the soil, stumps and other plant parts from previously existing plants can rapidly regenerate.

3-  The fertility and structure of the soil has also already been substantially modified by previous organisms to make it more suitable for growth and colonization.
