Eli5: What differentiates animals from other living things?
In: Biology
Animals are any multi cellular life that moves around on its own at some point in its life and eats stuff.
Plants are multi cellular life that photosynthesizes, and has a cell wall. They also dont move.
Fungi (mushrooms) are multi(ish) cellar life eat other stuff, has a differenter cell wall, and doesnt move about.
Turns out their isnt any species with multiple that moves and has cell walls or moves and photosynthesizes, so thats fine. Turns out moving takes a lot of energy and photosynthesis doesnt make much
Then there are a bunch of single celled stuff that just breaks all the rules, but its single celled so its fine.
