Organisms           -things that are alive
                    -any living thing

Dead                -when an organism is no longer alive
                    -something can only be dead if it once lived

Nonliving           -never alive

Living              -needs to meet two sets of requirements
                         -all organisms have needs
                         -all organisms must perform functions

7 Characteristics of Life
     -Needs      -gas exchange –gases move in and out of an
                       organism (doesn’t always mean breathing)
                 -water –sometimes comes from food
                 -use energy –this is why we eat
                 -eliminate waste – get rid of materials from food
                       that the organism cannot use

       -Functions         -respond to the environment – something
                                happens in the environment and the
                                organism responds
                          -grow – an increase in size
                          -reproduce (or the capability) – organisms
                                make more organisms of the same kind

Dormant -when something is alive, but is not demonstrating the
               characteristics of life
        -it is alive but inactive
        -when it is placed in the correct environment it will
        activate
