Biology is a study of life & comprises different levels from molecular to global. Biology is studying living organisms, and their organization and functions as well as biology are a large part of way environment evolved from very simple organisms & is intimately part of environment. The biology is a broad field, and covering very little workings of the chemical machines in our cells, and to the broad scale concepts of the ecosystems and the global climate change.

Biology is a study of life & comprises different levels from molecular to global. Biology is studying living organisms, and their organization and functions as well as biology are a large part of way environment evolved from very simple organisms & is intimately part of environment. The biology is a broad field, and covering very little workings of the chemical machines in our cells, and to the broad scale concepts of the ecosystems and the global climate change. The biologists study the subjects that range from the intimate details of human brain, composition of genes, and functioning of reproductive system for building blocks of simplest organisms on the earth that made oxygen rich atmosphere and capable to support the higher life forms. Without the biological processes we would not exist, and nor the planet since we know it.

The biological systems are vastly complex, and their function-based on the small numbers of atoms, molecules, cells, which are not at the equilibrium. Also, there are not any biological nature laws in the way that we find them in the physics; first & second law of the thermodynamics, Newton's law of gravity, Heisenberg's uncertainty principle, ands so on.

Supreme importance of role of the biology in environment is seen in case we consider biotechnology. Biotechnology, can usher in profound revolution do in early 19th century?
Biologists tolerate the level of ambiguity in the work that will drive average engineer and computer programmer crazy. Biologists can also see that the role of biology in an environment has also shaped our nature & being.
