1. 8 Processes of Life

2. 1. Life Cycle- all organisms are born, grow, and
die

3. Obtain Nutrients to create Energy-
Nutrients = food, water, and air
4 main nutrients: Carbon (C), Hydrogen (H), Oxygen (O),
and Nitrogen (N)
How is energy made?
Cellular Respiration–a process by which nutrients are broken down [digestion] and energy is created; oxygen needed

4. 3. Made of Cells – basic unit of structure and function
Unicellular = made of 1 cell
Multicellular = more than 1 cell

5. 4. Movement- move in some way at some point of life cycle
Ex: plants- Venus fly trap, leaves turn toward sun, roots
toward water
if microscopic-use tiny hairs or body changes shape
5. Reproduce –produce offspring to create new
generation, prevent extinction
asexual- 1 parent
sexual- 2 parents

6. 6. Excrete- eliminate wastes [unused portions of
what is taken in] to maintain healthy
chemical balance

7. 7. Respond to Changes in Environment-helps increase chance of survival
Stimulus- action organism reacts to [can be temperature, light, sound]
Response- reaction
Ex: environment temperature rises [S],
human sweats [R]
Why is this important?
Homeostasis- organism must be able to make constant adjustments to maintain stable conditions no matter what is occurring inside or outside of organism, if not survival decreases
Teachers' Domain: Fever!

8. 8. Adapt Over Time-any feature an organism
inherits to help increase its
chance of survival in its environment
Ex: Ant eater- long snout & tongue
Polar bear- white coat
