Secondary succession is much faster than primary succession because
pioneer colonizers are more
the soil is already present
secondary seeds require less nutrients
species competition is increased
Correct answer is A
Secondary succession is usually much quicker than primary succession for the following reasons:
There is already an existing seed bank of suitable plants in the soil.
Root systems undisturbed in the soil, stumps and other plant parts from previously existing plants can rapidly regenerate.
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.
