What does the prefix 'bio-' mean?

Explanation:
bio- means life. This prefix comes from the Greek word bios, which denotes living things and life processes. When you see bio- at the start of a word, it usually indicates something related to living organisms or life, as in biology, biodiversity, or biosphere. That connection to life is why this is the correct choice. The other prefixes point to other concepts—hydro- for water, geo- for earth, and photo- for light—so they don’t indicate life.
