Abiotic factors is any thing in a ecosystem that isn't living. Abiotic factors some times change by time like whether , whether is a abiotic factor that changes. Some examples are  weather,tempetare,sun,rocks and any thing that is not living.

Biotic factors are things in a ecosystem that is living it is the complete opposite of abiotic factors because abiotic factors are dead but biotic factors are not. We humans and animals are all biotic factors. We are biotic factors because we are living things.
