Prokaryotes, Eukaryotes, and Viruses

A | A rank–abundance curve showing marine prokaryotes and eukaryotes. The most abundant organisms in the ocean, such as SAR11, are probably K-selected organisms that have slow maximum growth rates but are resistant to viral lysis and grazing. By contrast, less abundant organisms, such as Roseobacter spp. and Vibrio spp., are capable of rapid growth but are highly…
