The diagram summarizes the flow of carbon through the carbon cycle. The components of the cycle that absorb and store carbon are called carbon sinks, while processes that release carbon to the atmosphere are called carbon sources.

Question

Deforestation is a process in which trees and other vegetation are removed from a section of land. What statement best describes the long-term consequences of deforestation on the carbon cycle?
A.
Less carbon will be stored in carbon sinks, so the level of atmospheric carbon may increase.
B.
More carbon will be stored in carbon sinks, so the level of atmospheric carbon may decrease.
C.
Less carbon will be released by carbon sources, so the level of atmospheric carbon may increase.
D.
More carbon will be released by carbon sources, so the level of atmospheric carbon may decrease.

Answer 1

A. Less carbon will be stored in carbon sinks, so the level of atmospheric carbon may increase.

Deforestation reduces the number of trees and vegetation available to absorb and store carbon, thus reducing the capacity of carbon sinks. This results in more carbon being released into the atmosphere, potentially leading to an increase in atmospheric carbon levels.
