It will be very difficult to say physics is more important than biology, vice versa. Both are important branches of science and have contributed immensely to the growth of science as a whole. Physics is a branch of science that deals with the study of the properties and interaction of time, energy, space, and matter.
This branch of science allows us to have a better understanding of the physical components or aspects of the universe. While physics doesn't have anything to do with the study of living organisms, it has made enough contributions to medical science, and other areas such as space exploration, weather, energy, etc. On the other hand, biology allows us to have a better understanding of the living world.
This branch of science has helped us understand how living things evolve, function, and interact. While you might think biology deals with life, the knowledge of physics is also guaranteeing our safety.
