What is the study of living organisms called?

The study of living organisms is called biology. This field encompasses various sub-disciplines that explore the structure, function, growth, evolution, distribution, and taxonomy of all living beings, from microscopic bacteria to complex mammals. Biology is fundamental for understanding the natural world and how living organisms interact with each other and their environments.

Physics, on the other hand, deals with the properties and interactions of matter and energy, focusing on forces, motion, and the fundamental laws that govern the universe. Chemistry involves the study of substances, their properties, and the reactions that occur when they interact, which is crucial for understanding the molecular basis of life but does not focus specifically on living organisms as a whole. Geology is the study of the Earth, its materials, and the processes acting upon it, concentrating on physical rock formations and the history of Earth over geological time rather than on living entities.
