What is the study of living things?

The study of living things is referred to as biology. This field encompasses the examination of various aspects of life, including the structure, function, growth, evolution, and distribution of living organisms. Biology is fundamental to understanding how organisms interact with one another and their environments, which is essential for various applications, including environmental conservation, medicine, and biotechnology.

The other options pertain to different areas of study: geometry focuses on the properties and relationships of shapes and spaces, chemistry is the study of matter and the changes it undergoes, and anatomy is specifically concentrated on the physical structures of organisms. Each of these disciplines is distinct and does not encompass the broader scope of living organisms that biology does.
