This simplified concept of energy flow has, over the past 30 years, been thoroughly criticized and reformulated (Pimm 1982, Polis and Winemiller 1994). Firstly, almost all organisms are omnivores in the sense that they feed on more than one tro闲逛 发表于 2025-3-25 20:26:55

These apparently contradictory observations indicate that residence times of the diverse miHumble 发表于 2025-3-26 03:40:46
Humic Substances as Ecosystem Modifiers — Introductionen humic lakes and clearwater lakes. In a two-dimensional diagram, there would thus be a continuum along the productivity axis from (ultra)oligotrophy to (hyper)eutrophy, while the humic lakes would stretch along the humus (or dissolved organic carbon) axis, yet at the very oligotrophic end.
