Biology is the scientific study of living organisms and their interactions with each other and their environments. It encompasses the examination of life at various levels of organization, from molecules and cells to organisms, populations, and ecosystems. Through observation, experimentation, and analysis, biology seeks to understand the processes and mechanisms that govern life, including genetics, evolution, physiology, ecology, and behavior. Ultimately, biology aims to uncover the fundamental principles that underlie the diversity and complexity of life on Earth.
