You might say it comes from plants, animals, or even fungi, but you'd probably rather not think about the rotting organisms and poop that feed those plants, animals, and fungi.
Ai putea spune că provine de la plante, animale şi ciuperci, dar probabil nu vrei să te gândeşti la organismele putrede şi excrementele ce au hrănit acele plante, animale şi ciuperci.
