3. 1- THEY ARE MADE OF CELLS Cells are the smalls units of life. Different types of cells have different “jobs” within the organism They are not composed of cells, but some people say there are alive; other people said they aren`t Differnts tips of cells

4. 2-RESPIRATION Organisms use the energy when the metabolize This energy is used to carry out everything they do

5. 3-NUTRITION FEEDING: Food provides energy to organisms: 1-autotrophs: Organisms that produce their own food 2-eterotrophs: Must ingest food in order to obtain energy

6. RESPONSIVENESS (IRRITIBILITY) STIMULE----RESPONSE (CAUSE)-----(EFECT) It is characteristic of living organisms that they react to changes in their surrondings
