What is the field of study that focuses on living organisms?

The field of study that focuses on living organisms is biology. It encompasses the examination of all aspects of life, including the structure, function, growth, evolution, distribution, and taxonomy of living things. Biology covers a vast array of topics, from cellular processes and genetics to ecosystems and behavior.

While botany, which specifically deals with plants, is indeed a branch of biology, it does not capture the full breadth of the study of all living organisms, which includes animals, microorganisms, and more. The other fields mentioned, physics and chemistry, pertain to the physical laws of the universe and the properties of substances, respectively, and do not center on biological life forms. Therefore, biology is the most comprehensive and accurately describes the study of all living organisms.
