The Sizes of Life On Earth

Life on Earth varies from the massively large as is the case with trees which reach heights of 100 meters and have a mass of 1000 tonnes, to the incredibly small as is with bacterium which are less than 1,000,000th (1 millionth) of a millimeter with a mass less than 10,000,000,000,000th (10 trillionth) of a gram. These differences span over 22 orders of magnitude in mass
