Short summary
Marine sediments are locations of carbon storage. Only some deposited carbon remains stored, while most is lost as CO2 through respiration by organisms. We report experiments to investigate the organisms responsible for marine sediment respiration. Larger organisms and microbes contributed equally to respiration. The groups competed to feed on fresh carbon. Respiration of older carbon was stimulated when both groups were present, thus burrowing activities allow microbial activity to increase.
