8 Processes of Life

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

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

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

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

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. 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
