Biology (from Greek Βìο meaning life and Λoγος meaning the study of) is the study of life. Biology encompasses a broad spectrum of academic fields that are often viewed as independent disciplines. However, together they address phenomena related to living organisms (biological phenomena) over a wide range of scales, from biophysics to ecology. It is concerned with the characteristics, classification, and behaviors of organisms, how species come into existence, and the interactions they have with each other and with the natural environment. There are however unifying features. All biological phenomena are subject to the same laws that other branches of science obey, such as the laws of thermodynamics and conservation of mass. Practically the continued existence of any biological organism is always dependant on acquiring sufficient energy to overcome deleterious entropic effects.

Many of the subdisciplines of biology, such as botany, zoology, and medicine are ancient. However, biology as a unified science first developed in the nineteenth century, as scientists discovered that all living things shared certain fundamental characteristics and were best studied as a whole. Today biology is one of the most prominent scientific fields. Over a million papers are published annually in a wide array of biology and medicine journals[1], and biology is a standard subject of instruction at schools and universities around the world.

As such a vast field, biology is divided into a number of subdisciplines. The old division by type of organism remains with botany encompassing the study of plants, zoology the study of animals, microbiology the study of microorganisms, and other similar disciplines. The field is also divided by the scale being studied: molecular biology looks at the fundamental chemistry of life; cell building block of all life the cell; Physiology looks at the internal structure of organism; and ecology looks at how various organisms interrelate.
