Reductionism is a scientific approach where complex systems (like the human body, ecosystems, or even behavior) are broken down into smaller, simpler parts to understand how the whole system works. Scientists use it to focus on specific components, making it easier to observe, experiment, and explain.For example:In biology, instead of studying the whole body at once, scientists may focus on cells, or even just DNA.In chemistry, compounds are analyzed by studying their individual atoms or elements.In psychology, human behavior might be studied through brain functions or hormones.
