Additional files [RJEE Vol. 5 (2). 2020 – 6] The share of consumption b of organic matter by heterotrophs in the ocean (solid lines, calculated in the present work) and in sustainable terrestrial ecosystems (dashed lines, taken from works [1, 14, 15]), depending on body size. The characteristic linear size L is related to live mass m through the relationship L (cm) = m1/3 (g1/3). The areas of hyperfine tuning corresponding to the largest body sizes are shaded in the hues of red
