I'm basically saying that you can see from the context (the numbers) that it's biomass - the same-ish as below even when/if the first thing you think about doesn't make sense, you search for the way it does (again, not dissing, but strictly technically it is about literacy, which in this case the pic is at fault for not all of the audience not getting it, and you for not understanding it, an overlap just didn't happen):
And yes, since this is pun-ish territory, it's normal to feel some anger, puns are there worst.
