Biology explores life, from tiny cellular structures to the living planet. This lesson introduces the breadth of biology and explains how it fits within science and the natural sciences.
Biology is the study of life. Its scope is exceptionally broad: biologists may investigate molecules and cells, individual organisms, populations, ecosystems, or processes affecting the entire planet. Questions about disease, food safety, biodiversity, and climate change all connect to biology.

What are natural sciences?
Fields that study the physical world and its processes, commonly including biology, physics, chemistry, earth science, and astronomy.
What is an interdisciplinary science?
A field that combines approaches from multiple disciplines; biochemistry combines biology and chemistry.
