SPEAKER: I look in that fridge and it's pretty disgusting. There are things that are oozing black liquid at the bottom. There's shrivelled up things in the corner. And there's a smell that I don't really want to ask where it came from. But where does all of that come from?

And the answer is decomposition. Because it turns out we aren't the only ones that eat food out of our fridges. There's bacteria and fungi in there that break down organic material and that's how they survive.

And so that's how you end up with broccoli that has its cell walls broken down. And so all of its water and nutrients and other liquidy things flow out and make this disgusting black ooze. And that's why you get the fats in meat being broken down, releasing this just terrible rancid smell. And that's why the inside of a peach gets eaten away and so there's nothing but the exterior, which collapses on itself, shrivelling up like I do in a social situation. And I guess if you want to know how that happens, we can find out.
