description: |
  Rate of biomass production by heterotrophs — herbivore, detritivore, and
  carnivore consumption converted to body tissue. In-situ measurement is
  fragmented across terrestrial herbivory studies, aquatic zooplankton
  monitoring (GLEON, ICES), and FAO fisheries catch statistics.
  GEO BON v3 (2023+) candidate EBV list subsumes secondary productivity
  under net primary productivity; this entry is retained for historical
  reference and is not in the current EBV canon.
