order
organisms are highly ordered and are all made up of at least 1 cell
reproduction
life comes from life (biogenesis) transfer of genetic traits onto offspring via genes
growth and development
directed by the information contained in the DNA
energy utilization
organisms take in and transform energy to do work, including the maintenance of their ordered state; metabolism
autotrophs
produce their own food (plants)
heterotrophs
acquire energy from the tissue of other organisms (animals)
response to environment
organisms respond to stimuli from their environment
homeostasis
organisms regulate their internal environment to maintain a steady-state, even with changing external envirnmments

evolution- change over time
adaptation
ability to utilize traits that improves the organisms survival in an environment
