“Marine microbes: Small but mighty at capturing carbon”
"Averaging a life span of just a few days, 30 million marine microbes would fit in a shot glass, 100 in the width of a human hair. These organisms are tiny – just a single cell – but powerful when it comes to sequestering carbon dioxide. Marine microbes comprise more than 98 percent of ocean biomass: microalgae, bacteria, archaea, protozoa fungi, and viruses. Together, marine microbes account for almost half of all photosynthesis on Earth: sunlight and carbon dioxide in – glucose and oxygen out."
