Biology is the science that deals with the study of living organisms. It encompasses a wide range of sub-disciplines, including microbiology, botany, zoology, and ecology, among others. Biologists explore the structure, function, growth, evolution, and distribution of living things, and they conduct research to understand complex interactions within ecosystems and the impact of environmental changes. The insights gained from biological studies are crucial for advancements in medicine, conservation, agriculture, and biotechnology, contributing to our understanding of life on Earth and its sustainability.
