The Entner-Douderoff pathway is an alternative to the Embden-Meyerhoff-Parnas pathway that allows breakdown of sugar acid substrates and allows gut microbiome members to feed on secreted mucus with such acids in the intestine. This is beneficial because the:
a) microbes stimulate the immune system and prevent pathogens from colonizing.
b) mucus increases the rate of digestion.
c) microbes induce the production of enzymes by the intestine.
d) additional mucus prevents the formation of ulcers

How does upwelling affect coastal fisheries? upwelling damages nutrient supplies at coastal fisheries as the warm, nutrient-rich surface water is replaced by nutrient-poor, cold water. upwelling damages nutrient supplies at coastal fisheries as the cold, nutrient-rich surface water is replaced by nutrient-poor, warm water. upwelling improves the nutrient supply at coastal fisheries as the warm, nutrient-rich surface water replaces the nutrient-poor, cold water. upwelling improves the nutrient supply at coastal fisheries as cold, nutrient-rich water replaces the warm, nutrient-poor surface water.
