Hi there, Biotic is a living factor, Abiotic is a non-living factor. All the below are biotic factors: bacteria . rotting log . rotting leave . I hope this helped and this is right! Have a nice day! Disclaimer: Now i'm not totally 100% sure on rotting log & leave, because a tree is alive but a rotting one? My guess would be yes its still alive until its dead, and the leave same thing but it was once apart of a living tree, but these are what i would put!
