Which outcome results when excessive upwelling removes bottom sediment nutrients?

💡 Explanation

When upwelling removes sediment nutrients, it diminishes the bioavailable phosphorus and iron because sediments provide stable reserves, leading to lower dissolved concentrations which limits phytoplankton populations. Therefore reduced phytoplankton productivity, results rather than algae blooms, because algae often thrive on excess nitrogen, and contrary to enhanced reef nutrient or consistent zooplankton populations, which depend on basal production.
