5. Use section 2.2 in the textbook Unit 5: Energy in Ecosytems
Title Page Write the topic for the unit in the middle of the paper and box it in. 2. Divide the paper into 3 equal sections. 3. Put a subtopic/key word in each section. 4. Add an appropriate picture to each section(no stick figures). 5. Each section must have 3 different colors(black and white don’t count). Don’t use the same 3 colors for 2 different sections. 99

8. What are the Laws of Conservation of Matter and Energy?
Law of Conservation of Energy-Energy cannot be created or destroyed but it can be transferred or transformed.
Law of Conservation of Matter-Matter(atoms) cannot be created or destroyed but it can be changed from one form into another.

9. What does food provide to organisms?
Matter
The atoms necessary to build the macromolecules that make up living things(remember NOCH!)
Energy
Food molecules are broken down by the process of digestion.
This releases energy that is stored in the chemical bonds.

10. What are Macromolecules?
Large(thousands of atoms)
Includes:
Carbohydrates-Made of C,H,O
Proteins-Made of C,H,O,N
Lipids-Made of C,H,O
And….
Nucleic Acids

11. Do all living things need food?
Producers are organisms that do NOT get their energy and nutrients from food.
They get their energy from radiant energy from sun.
It is turned into chemical energy by the process of photosynthesis.

12. What happens during photosynthesis?
CO2 and H2Oare taken in by the producer.
Glucose(C6H12O6) is assembled.
Powered by the radiant energy from the sun.
Glucose may be linked into larger molecules like starch

14. What is a consumer?
Organisms that get their energy and matter from food.
Take in the molecules stored in the bodies of other organisms.
The energy and elements in these molecules are released in a series of chemical reactions (digestion).
This is why the energy in food is called chemical energy.
