Primary consumers

Zooplankton and the benthic suspension-feeders are the primary consumers in the system. Their main food is phytoplankton. Zooplankton utilises the whole water column for food. The (adult) benthic suspension-feeders has a fixed position and the availability of food depends on their position and the water flows (tides). The figure show clearly that the highest biomass of filter-feeders is found near the channels.
