13 Which statement best describes the differences in species diversity between an ecosystem beginning the process of primary succession and one beginning the
process of secondary succession?
4
A Species diversity is much greater in the ecosystem undergoing primary
succession because that ecosystem is experiencing a longer period with a lack of
competition for space.
B No differences in species diversity exist because both ecosystems initially lack
living organisms.
C Species diversity is much greater in the ecosystem undergoing primary
succession because the lack of soil provides a greater area for organisms to
claim niches.
D Species diversity is greater in the ecosystem undergoing secondary succession
because the soil already contains seeds and spores of various species.
