Answer:
It was once alive.
Explanation:
Biotic factors are defined as the part of ecosystem which is alive, for example: birds, trees or plants, and humans and abiotic factors are the part of ecosystem which are not alive, for example: stone, rivers, and mountains.
A fallen, rotting tree is considered a biotic factor because it was once alive and was not dead from the beginning. Whereas abiotic factors are dead from the beginning and never lived.
