Which branch of science studies living organisms?

The branch of science that studies living organisms is called Biology. It explores the structure, function, growth, evolution, and behavior of all living things—from the smallest bacteria to the largest animals and plants. Biology is divided into many subfields such as botany (study of plants), zoology (study of animals), and microbiology (study of microorganisms). This field helps humans understand the complex systems that sustain life, including genetics, ecology, and physiology. Through biological research, scientists have discovered ways to fight diseases, preserve biodiversity, and improve agriculture. Biology also teaches us about the delicate balance between humans and nature, guiding us to live more sustainably. In essence, it connects life’s smallest details to the broader challenges of survival and health on Earth.
