Biology 🧫 is a natural science that studies living organisms and their interactions with the environment. It encompasses a wide range of topics, including the structure, function, and behavior of living organisms, the evolution and classification of species, the ecology of populations and ecosystems, and the cellular and molecular processes that underlie life. Biology is concerned with the study of life at all levels, from the smallest microorganisms to the largest ecosystems, and seeks to explain the fundamental processes that sustain life, such as metabolism, reproduction, and adaptation. Biologists use a variety of methods, including observation, experimentation, and modeling, to investigate the natural world and to develop new technologies and applications. The study of biology is essential for understanding the complexity and diversity of life on Earth and for addressing many of the pressing issues facing society, such as climate change, biodiversity loss, and disease.
