Biology is defined as the science of life, including the relationship between living things and their environment. Experts provide various perspectives on biology, including that it is the broad study of living things from millions of years ago to present (Nugroho and Sumardi), the science discussing life on Earth (R. Firmansyah), and a science related to life with branches studying different aspects of life (Fiktor Ferdinand P and Moekti Ariwibowo). Biology has benefits in fields like agriculture, health, pharmaceuticals, fisheries, industry, and energy development.
