Multiple Choice

How does succession affect species diversity after ecosystems are disrupted by an event such as the Mt. St. Helens volcanic eruption?

• Succession increases species diversity by allowing pioneer species to establish and modify the environment, facilitating the arrival of more species over time.
• Succession decreases species diversity by eliminating pioneer species and preventing new arrivals.
• Succession has no impact on species diversity after an ecosystem is disrupted by an event.
• Succession only benefits a few dominant species, reducing overall diversity in the ecosystem.
