Bacteria and Archaea: The Crucial Roles of Prokaryotes in Ocean Environments

The different kinds and functions of prokaryotes (bacteria and archaea) in the ocean are vast and multifaceted. These microorganisms are not only fundamental to marine life, but also play a critical role in global biogeochemical cycles and climate regulation. Their ability to thrive in diverse and often extreme environments highlights their adaptability and importance in maintaining the balance and health of marine ecosystems. As our understanding of marine prokaryotes continues to expand, so too will our appreciation of their vital contributions to the world’s ocean and the broader environmental processes they support.
