Figure 21From: Impact of polychaetes (Nereis spp. and Arenicola marina) on carbon biogeochemistry in coastal marine sediments†Balance between production of nutrients by microorganisms and uptake by assimilation or precipitation as a function of concentration (proportional to diffusion scale). Reaction is normalized to the maximum production rate and concentration is normalized to half saturation (Km) (modified from Aller and Aller[23]).Back to article page
