What is the study of life called?

• A. Biology
• B. Physics
• C. Chemistry
• D. Ecology

Answer: (A)

The study of life is biology. Biology is the science that explores living things—what they are made of, how they function, how they grow and develop, how they reproduce, how they evolve, and how they interact with each other and their environment. It covers a wide range of topics from the chemistry inside cells to the networks of ecosystems. The other options aren’t the broad study of life: physics looks at matter and energy and the laws governing them, chemistry focuses on substances and their reactions, and ecology is a branch of biology that specifically examines how organisms interact with each other and their surroundings. Since the question asks for the field that studies life in general, biology is the best answer.
