The Greek root word bio means 'life.' Some common English vocabulary words that come from this root word include biological, biography, and amphibian. One easy word that is helpful in remembering "bio' is biology, or the study of 'life'.
while we, the livestock and agricultural products, as well as others call 'bio', when they are staples, products and by-products not be 'bio', because they aren't in or with "life"... that repeat my question here, made earlier: Is it fair to the manufacturing of everything called bio products?
