Biology is the scientific study of living organisms and their interactions with each other and the environment. It encompasses a wide range of fields, including genetics, ecology, physiology, anatomy, evolution, and more.

At its core, biology seeks to understand the processes that underlie life, from the smallest molecules to the largest ecosystems. This can include studying the structure and function of cells, investigating the mechanisms of genetic inheritance, exploring the interactions between organisms and their environment, and examining the diversity of life on Earth.
