Ecology is the study of the interactions between living organisms and their environment. Genetics focuses on the study of genes and heredity. Biomechanics is the study of the mechanics of living organisms. Biochemistry is concerned with the chemical processes in living organisms. While each of these branches of science may touch upon aspects of the interactions between living organisms and their environment, ecology is the only one that specifically focuses on and encompasses the study of these interactions. Therefore, A (Ecology) is the correct answer.
