Okay so don't take this the wrong way when I ask this cause its for science. How many pill do you have to take too OD??

I think  depends

It depends on what medication/drug it is. Pharmaceutical drugs would be a lot before you could "od", some such as "xanax" take a short amount of time.

hope this helps!

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.

hope it ,
