What is Biology?

Biology is one of the vast disciplines of science that deals with living organisms and their evolution, functions, growth, and structure. Apart from the study of living things, the subject also specifically focuses on the concepts of ecosystems, environment, food quality, development in the health sector, diseases, and other specializations that revolve around the human body.
