United KingdomA study published in Functional Ecology reveals that certain sponge species in tropical coral reefs contribute significantly to ecosystem productivity through photosynthesis. Researchers from the University of Amsterdam's Institute for Biodiversity and Ecosystem Dynamics examined 24 common sponge species around Curaçao, finding that half of them accounted for 11% of gross primary productivity. This challenges prior assumptions that sponges were solely consumers in marine food webs. The study highlights the role of symbiotic photosynthetic microbes within sponges, which convert sunlight into energy and release oxygen. By using three-dimensional reef data, the team calculated sponge volumes and demonstrated their substantial contribution to organic compound production.
