Carbon flow dynamics within the microbial loop. (IMAGE)
Caption
Data analysis across P1 (days 0–16) and P2 (days 16–73) highlights the shift in carbon flow. The three circles represent the prokaryotic biomass at different time (Day 0, Day 16, and Day 73), where HNA and LNA are represented in red and blue, respectively, and the numbers represent biomass (μg L–1). Solid black arrows extending from each circle represent the daily average PBP-H (μg L–1 d–1), and dashed black arrows represent PBP-L. Red arrows ex- tending from each black arrow represent the daily average PMC (μg L–1 d–1), where solid lines represent PMC-H and dashed lines represent PMC-L. The three red rounded rectangles represent changes in HNF biomass at different stages. The gray dashed arrows represent alterations in carbon flow due to other pathways, calculated as the difference between total PBP, total PMC, and the change in prokaryotic and HNF biomass. The percentages in parentheses represent the ratio of PBP and PMC of LNA to total PBP and PMC.
