Can I digest wood?

Maybe the trace amounts of glucose held within, but the m as majority of wood is lignin and almost nothing can digest lignin.

Not even termites. They have a symbiotic protist that actually breaks down the lignin.

You also cannot digest cellulose.

Not at all in my opinion

You can if you are a beaver.

are you a termite ??????

No, unless you are a wood furnace

Sure you can, try some.

No actually! Cellulose cannot be digested by humans which is mostly what wood is.
