Answer
Brief Explanations:
Biotic factors are living or once - living organisms. A fallen, rotting tree was once alive, which is why it is biotic. Abiotic factors are non - living components like rocks or water. Just being part of an ecosystem or providing shelter doesn't define it as biotic; the key is its past life.
Answer:
It was once alive.
