barley cake, kneaded lump

Literally: life lump

The story of the word

The bio- half is plain Greek. The other half travelled further than it looks: English mass comes through Latin massa, which Latin most likely took from Greek μᾶζα, the flat barley loaf that fed the poor. Ecologists began weighing life under this name in the twentieth century, starting with plankton hauls; the fuel sense arrived much later and now dominates the word.
