Question 4 • Biology

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
building proteins
B
respiration
C
photosynthesis
D
decomposition

Explanation

Photosynthesis removes carbon dioxide from the atmosphere and stores the carbon in plants, helping counteract carbon released by burning fossil fuels and clearing or burning forests. Building proteins, respiration, and decomposition do not provide this same net removal of atmospheric carbon dioxide.
