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, record 1, English, - lower%20trophic%20level

The importance of oceans and the life within them is often understated. Oceans make up 71% of the Earth's surface, and produce 50-80% of the oxygen in the atmosphere ... A majority of this oxygen is produced by microscopic free-floating plants, also known as phytoplankton, which account for the majority of bottom trophic level production in most marine ecosystems. A large number of marine food webs are under "bottom-up" control, in which the quantity of primary production controls the abundance of individuals within trophic levels and their biomass. The Arctic marine ecosystem is thought to be under bottom-up control, where primary production is largely limited by advective nutrient supply from adjacent oceans ...  2, record 2, English, - lower%20trophic%20level%20production
