Does commensalism involve abiotic factors or biotic factors ?

Commensalism only occur among biotic factors

Explanation:

Abiotic factors are non-living factors that interacts with the biotic factor within an ecosystem. Commensalism is an association between two organisms in which one benefits and the other derives neither benefit nor harm.

From the above definition of commensalism, it is clear to note that it only involves two organisms rather than non-living organisms, hence; commensalism involves only biotic factors

not too sure but maybe in the hot springs.
