Since poop is the solid waste that the majority of organisms produce, how is it so packed with nutrients that plants like?
In: Biology
Plants are biological machines that get their energy passively from somewhere else (the Sun, through photosynthesis) and use that energy to *build* stuff (sugars). They’re a kid who sees a pile of random Lego bricks and decides to build things with it.
Animals are biological machines that take already-built stuff (food) and break it apart to liberate the energy stored within (eating), and then discard the remains (poop). They’re the bully who sees built Lego creations and gets their jollies smashing them to pieces, taking the parts they think would be cool for their spaceship and leaving the rest behind.
A kid who wants to build with Lego needs a supply of pieces to build with. While it’s certainly not a good thing if a bully come along and smashes *their* stuff, a bully who smashes *someone else’s* stuff and then conveniently carries the pieces to the builder kid and leaves them lying around for the builder kid to play with is certainly welcome. It’s all waste to the bully, they have no intention of making anything with those pieces. But the builder kid sure is stoked to have new things to build with.
