Polite reminder: Earth is a tree planet with some bacteria. Everything else is just the extra stuff that lives here too.

For everyone who found this interesting, the research paper it originally came from us Bar-On et al (2018) and it's free to read here:

Interestingly, the biomass distribution on Earth is overwhelmingly terrestrial, because most biomass is plants and most plant biomass is trees (with some other woody biomass like shrubs and things).

After terrestrial, a big slice is deep subsurface, which is mostly microbes.

Marine biomass is a surprisingly small fraction considering how much of Earth is ocean. Most ocean life is apparently animals and protists.

This has become a bit of a rabbit hole. As all the most interesting things tend to.

I have never regretted the places unreasonable curiosity has taken me
