Why is the interdependence of the worms and plants an example of commensalism?

The interdependence of the worms and plants is an example of commensalism in a sense that as the worms burrow into the soil, it allows the soil to be loosened which then allows it to properly absorb water and carbon dioxide into its roots. This action benefits the plants' growth. However, such action of the worms, neither benefit the worms nor does it cause any harm.

Explanation:

"Commensalism" is a relationship between two things wherein one benefits while the other is neutral. This means the other one doesn't benefit nor is it harmed.
