Which ecosystem effect occurs when substantial tephra deposition blankets a landscape?

💡 Explanation

Initial nitrogen deficiency occurs because tephra buries organic matter preventing decomposition; the mineralization process cannot release fixed nitrogen. Therefore the initial soil chemistry inhibits early succession, rather than immediately promoting biodiversity or algae growth.
