What is a primary effect of a volcanic eruption on species diversity in an ecosystem?
30
It creates new land that can support new species over time.
It increases pollution which affects species negatively.
It leads to immediate extinction of all species.
It has no effect on the species diversity.

How does secondary succession differ from primary succession in terms of the starting conditions?
30
Secondary succession only happens in aquatic environments.
Secondary succession occurs in areas where soil is already present.
Secondary succession occurs on newly formed volcanic islands without soil.
Secondary succession starts with barren rock surfaces.
