Which outcome results from widespread bioturbation in mangrove ecosystems?

💡 Explanation

Bioturbation—the reworking of sediments by organisms—churns anoxic sediment upward, exposing sulfides to oxygen and increasing sulfide oxidation rates, because this physical mixing enhances chemical reactions. This occurs rather than decreasing rates, therefore supporting energy flow within the ecosystem.
