and energy and matter continually recycles through systems as energy flows through the systems

Life & Cells Obey Physical/Chemical Laws of the UniverseAll living things are parts of larger systems of matter and

energyMatter is continually recycled through systems as energy

flows throughThere is no unique law defining the living state separate

from different natural/physical laws* Cells extract energy Transform energy

Capturing light Redox reactions Electron flow

Expend energy to maintain an ordered state
