"Biodegradable" includes the prefix "bio-," which also appears in words such as "biology" and "biosphere." Based on what you know about those words, what does "bio-" mean?

Live it up if you picked answer B! The prefix "bio-" comes from the Greek word for "life." When you see a word with "bio" in it, think of something having to do with living things. As you probably know, "biology" is the study of living things, and the "biosphere" is the part of the earth where organisms can live.
