The differences between chaotic, orderly and complex.

Something that is chaotic is not organized and it does not have order. For example, paper that is scattered all over a desk is considered chaotic because it is unorganized and random. The alphabet can be orderly system because it is always used in that order. A fractal is complex and it repeats in a pattern that is complicated.

How is environmental science different from other science like biology and chemistry ?

Environmental science is different from other fields of science because it involves the way the environment affects humans and other organisms. Biology only covers the study of life and chemistry is based on the chemicals and their reactions with other substances. Environmental science also involves the idea of chaos, order, and complexity. A series of random events can produce complex, orderly systems. For example, a checkerboard is a highly orderly "system."
