Question 4 • (OC27) Earth/Space Sci-2001310-S1-Nelson

Humans affect the carbon cycle in many ways through the use of fossil fuels, clear cutting of forests, and controlled burns. Which process can help counteract these human interactions?

Answer
A
photosynthesis
B
respiration
C
decomposition
D
building proteins

Explanation

Photosynthesis takes in carbon dioxide from the atmosphere and uses it to make sugars, storing carbon in plants. This can help counteract human activities that release carbon dioxide or reduce the number of trees that absorb it. Respiration and decomposition generally release carbon dioxide back into the atmosphere.
