Explanation:

Abiotic factors are non - living components of an ecosystem. An oak tree (A) is a living organism (biotic). A dead, broken branch (B) was once part of a living tree, and its origin is biotic, though it may be in a decaying state. A mushroom (C) is a living fungus (biotic). A sand particle (D) is a non - living component of the environment, so it is an abiotic factor.
