From: Subcellular view of host–microbiome nutrient exchange in sponges: insights into the ecological success of an early metazoan–microbe symbiosis

Schematic overview of organic matter uptake by the HMA species P. angulospiculatus and LMA species H. caerulea and hypothesised pathways of nutrient recycling by the microbiome. The width of arrows represents expected quantitative difference in fluxes: choanocyte processing pathways are based on NanoSIMS data (this study) and putative microbially mediated pathways are based on published data (partial transcriptional or genomic evidence included) [20, 28, 69,70,71,72,73,74]. Internal nitrogen recycling pathways are hypothesised to be elevated in HMA vs. LMA species [13, 49]. Host amoebocyte cells digest material passed from food capture cells (not shown), and in HMA species, these cells are prolific consumers of microbial symbionts (this study, [39])
