Wetlands: filter nutrients, carbon sink: absorb carbon in the air, nursery grounds for small animals (biodiversity) Indication of eutrophication: change in diatom community (increase in the centric pinnate diatom ratio) Limit phytoplankton growth: freshwater: p-limited, marine (salt water): n-limited.
