WebSep 12, 2024 · The share of phytoplankton grazing is only 20.9%, which is inconsistent with the idea that most of the phytoplankton production is consumed as food in the pelagic food chain. Thus, according to previous studies, primary consumers take about 60% of phytoplankton production, and about 10% is used in the benthic food chain (Karpevich, … WebJul 3, 2024 · There are a number of marine animals that live in the mesopelagic zone.

A number of food web config-urations can be envisioned depending on the extent of trophic flows between littoral and pelagic food chains. At one extreme is the scenario of two unlinked food chains, indicating food chain specialization on the part of consumers. Webfood chain length in pelagic ecosystems, compared with terrestrial ecosystems, is associated with smaller pelagic animal body size per-mitting more rapid trophic energy … psyched clue
