Tha bith-mhoileciuil na mhoileciuil a tha an làthair gu nàdarra ann am fàs-bheairtean. Tha bith-mhoileciuilean air an dèanamh gu ìre mhòr air gualan is haidridean, le naitridean, ogsaidean, fosfaras agus pronnasg nam broinn. Tha eileamaidean eile uaireannan nan lùib, ach chan eil iad a cheart cho cumanta.
