I've seen another image which shows cubes indicating total biomass inclusive of plants and invertebrates. Humans aren't quite so prominant on that, though as a measure of all animal biomass, still a large fraction.
This ... is close though not quite what I had in mind:

And NB, that's not the xkcd "Land Mammals" one, though that's also impressive: https://xkcd.com/1338/
One is the instantaneous biomass at any point in time.
The second would be something like "rate of new biomass formation".
A human lives ~82 years, a cow lives ~3, a chicken lives ~6 weeks (for a fryer or broiler). The human lives ~715 times longer than the chicken, but weighs only 30 times more. There's nearly 25 times more chicken biomass cycled per year than human.
(The fact that that chicken biomass goes to feed the human biomass is also a part of this, of course.)
A good proxy would be to multiply the number of animals by the Animal Unit Equivalents (AUE).
