8 Processes of Life8 Processes of Life

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

2.2. Obtain Nutrients to create Energy-Obtain Nutrients to create Energy- in the form of

food, water, and air 4 main nutrients4 main nutrients: Carbon (C), Hydrogen (H), Oxygen (O), and Nitrogen (N)

How is energy made?How is energy made?

Cellular RespirationCellular Respiration–a process by which nutrients are broken down [digestion] and energy is created; oxygen needed

3. Made of CellsMade of Cells – basic unit of structure and function

Unicellular Unicellular = made of 1 cell

MulticellularMulticellular = more than 1 cell

4. MovementMovement- move in some way, many forms

Ex: plantsplants- Venus flytrap, leaves turn toward sun, roots toward water

5. Reproduce Reproduce –produce offspring to create new generation, prevent extinctionasexualasexual- 1 parent

sexualsexual- 2 parents

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

7. Respond to Changes in Environment7. Respond to Changes in Environment-helps increase chance of survival

StimulusStimulus- action organism reacts toResponse-Response- reaction

Ex: environment temperature rises [S], human sweats [R]

Why is this important?Why is this important?

Homeostasis- Homeostasis- organism must be able to make organism must be able to make constant adjustments to maintain stable constant adjustments to maintain stable conditions no matter what is occurring inside or conditions no matter what is occurring inside or outside of organism, if not survival decreases outside of organism, if not survival decreases

Teachers' Domain: Fever!

8. Adapt Over TimeAdapt 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
