**__ Life functions __** --are all the things that living things do to stay alive!

1. **__ingestion__** - the taking in of food - also called nutrition

2. **__digestion__** - the breaking down of food to a form that can be used for the life functions

3. **__respiration__** - the release of energy by combining oxygen with digested food - water and CO2 are waste products - cellular respiration

4. **__excretion__** - getting rid of waste products

5. **__circulation__** - the movement of useful products to all parts of an organism and the carrying away of waste products - also called transport

6. **__response to stimuli__** - reacting to changes in the environment
