Order - this is true at multiple levels; molecules - structures within cells - cells - groups of specialized cells (if multicellular - relationships among individual organisms: 2. Reproduction - asexual (single celled organisms, ancestral to sexual reproduction), death is a feature of life, viruses rely on others for successful reproduction: 3. Growth and development - new individuals grow and develop based on incorporation of materials and energy and heredity: 4. Energy utilization - the foregoing all require energy, in order to resist entropy organisms require energy: 5. Response to environment - also known as irritability, responses to non-living (abiotic) stimuli like temperature and living (biotic) stimuli like fleeing a predator: 6. Evolutionary adaptation - represents the match between the features of an organism and the opportunities and constraints of its environment (natural selection)
