Q: What is the ranking of the following in terms of their collective weight on Earth: bacteria, humans, and ants?

A: The sum total weight of all humans now living on Earth is about the same as the total weight of ants. Bacteria, when counting all subterranean bacteria, probably has a total weight that is 10 times the weight of all humans. In fact, humans may carry nearly 10 pounds of bacteria inside of themselves. If you make that 40 pounds it would account for the anomalous gravitational readings made on my bathroom scale.
