"The rate of viral infection in the oceans stands at 1 × 10^23 infections per second, and these infections remove 20–40% of all bacterial cells each day." - https://www.nature.com/articles/nrmicro2644

What are the equivalent figures on land?

    $\begingroup$ "On land" is pretty vague in this context. Are you just interested soil? Would you include surface waters? Wetlands? Animal-associated microbiomes? I think it's a simpler calculation for oceans, as marine biomass is largely dominated by microorganisms, whereas terrestrial biomass is dominated by plant life. $\endgroup$

  • $\begingroup$ True, it is vague. I'd be interested in figures for any non-ocean ecosystems. Animal and soil microbiomes in particular. $\endgroup$
