One significant knowledge gap necessary for assessing ecosystem-wide impacts of restoration in ... estuaries is a characterization of baseline lower trophic levels. These lower tropic levels are the lowest part of the food web where organisms such as plant-like phytoplankton serve as food to animals such as zooplankton in the water column. Other organisms of lower trophic levels include plant-like microphytobenthos and marine worms living within the sediments. These organisms form an important part of the estuary ecosystem [and] provide energy at the base of the food chain [that] support the growth of larger predators at the top[,] such as speckled trout or red fish[. These] organisms also help to break down debris, put oxygen back into sediments, and can provide a biological window into the health of an estuary.  1, fiche 1, Anglais, - lower%20trophic%20level
