Why are an organism, a cell and a population called biosystems?

Each biosystem (like any system) is a set of elements (components) connected into a single whole that perform certain functions. The interrelationships of such elements reflect the structure of the system, the complexity of its organization. Integrity, discreteness and a certain stability in space and time are also inherent in biosystems. Therefore, the organism, cell and population can be classified as biosystems.
