Explanation
A biologist is a scientist who focuses on living organisms, including plants and animals. Wildlife biologists might specialize in studying African elephants. Biologists study a wide variety of life forms, from single-celled organisms to primates, and conduct research in many different areas, from the spreading of pathogens to the details of evolution. A marine biologist studies sea creatures and a microbiologist might study algae or bacteria. The word biologist is rooted in the Greek bios, or "life."
