Prochlorococcus

Prochlorococcus is a tiny, photosynthetic marine microorganism, a type of cyanobacteria that plays a crucial role in Earth's ecosystem. It is among the most abundant photosynthetic organisms in the ocean, contributing significantly to global oxygen production and carbon dioxide absorption. Prochlorococcus thrives in sunlit surface waters, using sunlight to produce energy and organic matter through photosynthesis. Its small size and high efficiency allow it to dominate large parts of the ocean's microbial community, making it vital for maintaining the health of marine environments and the overall balance of the Earth's climate.
