The term for the study of living organisms is biology. This broad field encompasses various sub-disciplines, including zoology (the study of animals), botany (the study of plants), microbiology (the study of microorganisms), and ecology (the study of ecosystems). Biologists investigate the structure, function, growth, evolution, and distribution of living things, and their research can be applied in areas such as healthcare, environmental science, and biotechnology. Biology is essential for understanding the complexities of life and addressing challenges related to health, agriculture, and conservation.
