“…Foraminifera in general play an important role in the transfer of bacterial and algal products to higher trophic levels. It known from our own observations (Sergeeva et al, 2017;Sergeeva, Anikeeva, 2018) and published studies (e.g., Lipps, Valentine, 1970;Murray, 2006;Suhr et al, 2008), that these protists are omnivorous, feeding on small bacteria, algae, pollen of terrestrial vegetation, fragments of marine mycelial fungi, as well as on protozoans and multicellular invertebrates. In turn, they serve as an important source of food for many benthic invertebrates in various habitats.…”
