Among the tiniest living things in the ocean are a group of single-celled microbes called Prochlorococcus. They are cyanobacteria, also known as blue-green algae, and they supply nutrients for animals all the way up the food chain. Over 75% of surface waters teem with Prochlorococcus, but as ocean temperatures rise, researchers fear that the water might be getting too warm to support the population. Prochlorococcus is the most abundant photosynthesizing organism in the ocean, accounting for 5% of global photosynthesis. Because Prochlorococcus thrive in the tropics, researchers predicted that they would adapt well to global warming.
