KnowWhat does a living organism need to stay alive?

EvidenceMake 6 quick sketches showing the needs of living organisms.

Needs to live

- use sun’s energy, H- use sun’s energy, H22O, and carbon dioxide to make their own O, and carbon dioxide to make their own food.food.

autotroph

Clarifying ?s Information

heterotroph - needs help to get food – eat autotrophs or other heterotrophs- needs help to get food – eat autotrophs or other heterotrophsExample: plants

Example: animals, mushrooms, slime molds

1. Energy

2. Water – Without H2O, food can’t be broken down to grow, reproduce, or disolve chemicals in the body

4. Stable internal conditionsExample: maintaining fluid pressure in the cell

homeostasis - Maintain stable internal conditions – even when outside conditions - Maintain stable internal conditions – even when outside conditions change.change. Example: body temperature

cell theory - Explains the relationship between cells and living things – no - Explains the relationship between cells and living things – no matter how big or how smallmatter how big or how small

3 parts of theory

1. All living things are made of cells.2. Cells are the basic unit of structure & function in living organisms.

3. All cells are produced from other cells.
