3. Why do living organisms eat food?

4. HOW do living organisms get energy from the food they eat?

5. Digestion is a process that breaks food down into smaller particles so that energy can be obtained

7. What is food made of? Research on your phones…
What types of atoms make up food?

9. All the molecules have carbon and hydrogen=HYDROCARBONS
What is food made of?
All the molecules have carbon and hydrogen=HYDROCARBONS
***Hydrocarbons
contain hydrogen and oxygen atoms
We use hydrocarbons as fuel (fossil fuels)
All proteins, carbohydrates, and fats are hydrocarbons

10. Photosynthesis in plants
Chloroplasts
Produces Carbon Dioxide and Water and energy for the animal to move, grow, reproduce
Respiration in animals
Produces Sugar and Oxygen
Mitochondria

12. Respiration
Photosynthesis
Plants
Animals
Chlorplasts
Mitochondria
Make energy
For growth,
repair, and
reproduction
These processes are equal and opposite. They depend on each other for survival
