Question 65

Which of the following statements best describes "carbon fertilization"?

AOptions

A
A) Increased plant growth due to increased concentration of carbon dioxide in the atmosphere
B
B) Increased temperature of Earth due to increased concentration of carbon dioxide in the atmosphere
C
C) Increased acidity of oceans as a result of increased concentration of carbon dioxide in the atmosphere
D
D) Adaptation of all living beings on Earth to the climate change brought about by the increased concentration of carbon dioxide in the atmosphere

BSolution

"Carbon fertilization" refers to the phenomenon where an increased concentration of carbon dioxide (CO2) in the atmosphere leads to an increase in the rate of photosynthesis in plants. Since CO2 is a key ingredient for photosynthesis, higher atmospheric CO2 levels can, under certain conditions (like sufficient water and nutrients), stimulate plant growth. This effect is often considered when modeling the impacts of rising atmospheric CO2 levels on terrestrial ecosystems and the global carbon cycle.

While increased CO2 also contributes to increased global temperature (greenhouse effect) and ocean acidification, 'carbon fertilization' specifically describes the effect on plant growth.
