hey. i've looked every where. i'm getting so confused.
i need to know why fermentation is classified as a biological process.
i'm not sure why. some things say its fungi and others bacteria and others enzymes...
You are absolutely correct that yeast is a living organism!
What I was being pedantic about earlier (and apparently still am ) is that a living organism does not necessarily have to be an animal, although the reverse is true, as animals are a subclass of living organisms.
Yeast is a unicellular living organism that is classified as a fungus, so strictly speaking it's not an animal.
