Biologist is a scientist who studies living organisms and their interactions with their environment. Biologists use various scientific methods to understand the diversity of life on Earth, from the smallest microorganisms to complex ecosystems. They may specialize in areas such as genetics, ecology, physiology, molecular biology, or biotechnology, among others. Biologists may work in academic research, industry, government, or non-profit organizations to conduct experiments, collect data, analyze findings, and communicate their discoveries to other scientists and the public.
