Vexen Crabtree's Blurty

Invisible life!
I've added the following quote to "The Food Chain: Photosynthesis and Trophic Levels" by Vexen Crabtree (2007):

“A spoonful of good quality soil may contain ten trillion bacteria representing 10 000 thousand different species! In total, the mass of micro-organisms on Earth could be as great as a hundred trillion tonnes - more than all the visible life put together.”
"The Origin of Life" by Paul Davies, p22
