8 Processes of Life

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

2.Obtain Nutrients to create Energy- 2.Obtain Nutrients to create Energy- in the form of food, water, and air 4 main nutrients 4 main nutrients: Carbon (C), Hydrogen (H), Oxygen (O), and Nitrogen (N) How is energy made? Cellular Respiration Cellular Respiration–a process by which nutrients are broken down [digestion] and energy is created; oxygen needed

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

Movement 4. Movement- move in some way, many forms plants Ex: plants- Venus flytrap, leaves turn toward sun, roots toward water Reproduce 5. Reproduce –produce offspring to create new generation, prevent extinction asexual asexual- 1 parent sexual sexual- 2 parents

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

7. Respond to Changes in Environment 7. Respond to Changes in Environment-helps increase chance of survival Stimulus Stimulus- action organism reacts to Response- 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!

Adapt Over Time 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

Cellular Respiration 6. Cellular Respiration– breaking down food [digestion] to create energy; requires oxygen Excrete 7. Excrete- eliminate wastes [unused portions of what is taken in] to maintain healthy chemical balance Respond to Environment 8. Respond to Environment-helps increase chance of survival Stimulus Stimulus- what organism reacts to- action Response Response- reaction Ex: fly buzzes by horse [S], Horse swats tail to remove fly [R]
