2. Carbon is restored to the atmosphere by all of the following except:

*
20 points
cellular respiration
photosynthesis
forest fires
burning of fossil fuels
3. Which of the following is NOT a way that humans can reduce carbon emissions?
*
20 points
Reduce carbon emissions in factories/cars
Use clean energy like solar or wind
Cut down more trees
Recycle
4. Which of the following is the most accurate and complete definition of the carbon cycle?
*
20 points
The process that occurs when an animal dies and decomposes
The exchange of carbon as it is recycled and reused
Something that happens when we breath out
The depletion of carbon in the Earth’s atmosphere
5. Why do humans need to be aware of how much carbon dioxide they emit into the atmosphere?
*
20 points
Carbon dioxide is trapping heat and can affect climate change
Plants cannot absorb the carbon dioxide for photosynthesis
If too much carbon dioxide is emitted, decomposers cannot do their job
Carbon dioxide has a natural cooling effect, which can affect climate change

Here are the answers to your questions:

2. Carbon is restored to the atmosphere by all of the following except:

  • Photosynthesis. (Photosynthesis removes carbon dioxide from the atmosphere and converts it into glucose, effectively reducing atmospheric carbon levels.)

3. Which of the following is NOT a way that humans can reduce carbon emissions?

  • Cut down more trees. (Cutting down trees would increase carbon emissions, as trees absorb carbon dioxide. The other options contribute to reducing emissions.)

4. Which of the following is the most accurate and complete definition of the carbon cycle?

  • The exchange of carbon as it is recycled and reused. (This definition encapsulates the processes through which carbon is transferred between the atmosphere, land, water, and living organisms.)

5. Why do humans need to be aware of how much carbon dioxide they emit into the atmosphere?

  • Carbon dioxide is trapping heat and can affect climate change. (Excess carbon dioxide in the atmosphere contributes to the greenhouse effect, leading to global warming and climate change.)
