How does pneumonia disrupt homeostasis?

It disrupts homeostasis by putting our body in stress which isn’t good. It fills out alveoli with mucus and our bronchiole is inflamed with music. Besides, it shortens our breathe

The carbon cycle is definitely an example for a biogeochemical cycle -  The nitrogen and oxygen cycles are biogeochemical cycles too! so the last statement is true.

The biogeochemical cycle includes also for example the movement of water which is nonliving, so a) is also true.
The false statement is b) since the rock cycle does not include any biomatter.
