By definition, science is the study of the physical world and it manifestations, by using systematic observation and experimentation. Nature, on the other hand, is the actual physical world including all natural phenomena and living things. Both are made up of rules that can be rooted in the concept's governing dynamics. Laws of physical science are laws that are taken to be universally applicable. Laws of nature form the basic theoretical structure of the physical sciences, so that the rejection of a law by the scientific community is an extremely rare event. On occasion a law may be modified. Yet such modifications remain embedded in the original thought and structure that were acquired in the first instance. .
The numerous forms of science investigate the nature and behavior of matter and energy on a vast range of size and scale. These scientists also study matter elsewhere in the universe, including the planets and stars whilst at the same time examining the structure and composition of our planet, and the physical processes that have helped to shape it. Science has been shaped to examine all areas that deal with living things. As well as working with individual organisms, life scientists investigate the way living things interact. Their work helps to answer questions about one of the key characteristics of life, the fact that most living things maintain a steady internal state when the environment around them constantly changes. This change is due to technology. In technology, scientific knowledge is put to practical ends. This knowledge comes chiefly from mathematics and the physical sciences, and it is used in designing machinery, materials, and industrial processes.
The natural environment has certain attributes, among them dominance and species diversity. Dominance results when one or several species control the environmental conditions that influence species and aspects associated with that specific environment.
