|
Definition
- Carbohydrates
- Proteins
- Lipids
- Nucleic acids
|
|
|
Term
List five forms carbon can take as it recycles in the biosphere. |
|
Definition
- Part of a human
- Part of a plant
- Free-floating carbon dioxide
- Locked away in the shell of a sea creature
- Part of a volcanic eruption
|
|
|
Term

|
Definition
- Photosynthesis (MAIN FOCUS)
- Respiration (MAIN FOCUS)
- Decomposition
- Combustion of Fossil Fuels
- Natural Weathering of Rocks
|
|
|
Term
|
Definition
The process by which plants capture carbon dioxide and convert it to simple sugars. |
|
|
Term
How do animals obtain the element carbon? |
|
Definition
They eat plants or other animals that have eaten plants. |
|
|
Term
Name three types of organisms that carry out the process of respiration. |
|
Definition
Plants, animals and decomposers. |
|
|
Term
|
Definition
Respiration is the process used to break down organic compounds into carbon dioxide. |
|
|
Term
What is the photosynthesis process? |
|
Definition
Energy + carbon dioxide + water (Reactante)
--------> (Yields)
Glucose + oxygen (Products) |
|
|
Term
What is the equation for photosynthesis? |
|
Definition
Sunlight (energy) + 6CO2 (carbon dioxide) + 6H2O (water)
------->
C6H12O6 (glucose) + 6O2 (oxygen) |
|
|
Term
Describe the process of decomposition. |
|
Definition
Decomposers consume both dead matter and waste products and return it in to the atmosphere through respiration in form of carbon dioxide. |
|
|
Term
Where do decomposers live? |
|
Definition
Mostly in the soil and in water. |
|
|
Term
How have humans added to the carbon cycle in recent years? What impact does this have? |
|
Definition
By burning fossil fuels. The earth's atmosphere traps the carbon dioxide because carbon dioxide is a greenhouse gas and the trapped gas leads to a global temperature rise. Causes more CO2 emissions. |
|
|
Term
What type of organism releases the largest amount of oxygen into the atmosphere? During what process is this oxygen created? |
|
Definition
- Phytoplankton (produces 75% of oxygen)
- Photosynthesis
|
|
|
Term
What do plants do with carbon dioxide? |
|
Definition
- Use photosyntheiss to make glucose.
- Glucose = C6H12O6
- CO2 + H2O ------> C6H12O6

Term
What is fast-track carbon cycling? |
|
Definition
The flow of carbon between atmosphere, plants, animals and decomposers. |
|
|
Term
Identify two ways that carbon stored in slow track cycling makes its way back to the earth's surface. |
|
Definition
- Weathering
- Mining coal and natural gas
|
|
|
Term
How is carbon returned to the atmosphere during slow-track carbon cycling? |
|
Definition
Combustion of fossil fuels. |
|
|
Term
What is the earth's largest carbon reservoir in? |
|
Definition
|
|
Term
What is the key to sustaining the earth? |
|
Definition
Balence carbon dioxide users and recyclers. |
|
|
Term
What are three ways to promote a sustainable earth? |
|
Definition
- Conserve energy
- Manage forests
- Alternate fuel sources
|
