how many viruses, bacteria, plants and animals on earth?



How much viruses on planet earth? 10^31 based on Carl Zimmer's blog.

http://www.virology.ws/2009/10/19/ten-cool-facts-about-viruses/

http://phenomena.nationalgeographic.com/2013/02/20/an-infinity-of-viruses/

Quote from Carl Zimmer's blog:
RNA viruses made up between 38 and 63% of the viruses in the sea water. In other words, about half of the viruses in the ocean are RNA viruses.


viruses invented DNA?

Total number of bacteria on planet earth
http://www.sdearthtimes.com/et0998/et0998s8.html
5x10^30 (Hmm, this is only half of the 10^31 viruses of Carl Zimmer's blog).

How many single-cell organisms on ocean floor? 2.9x10^29
http://www.nature.com/news/there-are-fewer-microbes-out-there-than-you-think-1.11275
(Who this would include prokaryote, archea, and eukayote).

I did not find quotes on how many plants and animals on earth.

June 17, 2015 Biomass of plants, animals, fungi, prokaryotes, viruses are summarized in the following plos biology paper.
