An approach to studying biology that aims to model the dynamic behavior of whole biological systems based on a study of the interactions among the system's parts. Other examples include the synthesis of large proteins from amino acid building blocks and the synthesis of new DNA strands from nucleic acid building blocks. Biological processes are those processes that are vital for an organism to live, and that shape its capacities for interacting with its environment. All biological organisms require energy to survive. The same principle applies to molecules. Moving water, such as in a waterfall or a rapidly flowing river, has kinetic energy. The flight muscles in birds are extremely efficient in energy production. In summary, all living organisms require energy for both survival and reproduction.
