2. Needs of Living Organisms LT: I will be able to identify the 4 essential conditions for all living organisms 10/25/12 pages 37-38

3. Know What does a living organism need to stay alive? Evidence Make 6 quick sketches showing the needs of living organisms.

4. Needs to live - use sun’s energy, H 2 O, and carbon dioxide to make their own food. - use sun’s energy, H 2 O, and carbon dioxide to make their own 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 heterotrophs Example: plants Example: animals, mushrooms, slime molds 1. Energy 2. Water – Without H 2 O, food can’t be broken down to grow, reproduce, or disolve chemicals in the body Needs of Living Organisms 3. Living space – Shelter with others or compete for space.

5. Clarifying ?s Information Summary: Needs of Living Organisms 3. Living space – Shelter with others or compete for space. 4. Stable internal conditions Example: maintaining fluid pressure in the cell homeostasis - Maintain stable internal conditions – even when outside conditions change. - Maintain stable internal conditions – even when outside conditions change. Example: body temperature cell theory - Explains the relationship between cells and living things – no matter how big or how small - Explains the relationship between cells and living things – no matter 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.
